Inserting multiple array into database in Laravel

Hello Good day everyone, Please i am trying to insert into my database multiple allowance and deduction when creating a new employee in my project.

Datas passed through to The AllowanceUser and DeductionUser model are not been saved. But user and account model datas are saved

Using dd($input) the datas passed through are shown for all model

Below is my current code

         //Creating User model Instance 
        $user = new User();


        // accepting User model datas
        $user->employee_name = $request->input('employee_name');
        $user->email = $request->input('email');
        $password = Hash::make($request->input('password'));
        $user->password = $password;
        $user->date_of_birth = $request->input('date_of_birth');
        $user->gender = $request->input('gender');
        $user->phone_number = $request->input('phone_number');
        $user->nationality = $request->input('nationality');
        $user->address = $request->input('address');
        $user->marital_status = $request->input('marital_status');
        $user->department_name = $request->input('department_name');
        $user->designation_name = $request->input('designation_name');
        $user->resumption_date = $request->input('resumption_date');
        $user->employee_status = $request->input('employee_status');


        //Checking if file upload is present 

        if ($request->hasFile('user_photo')) {
            // Get file name with extension
            $fileNameWithExtension = $request->file('user_photo')->getClientOriginalName();

            //Get file name only
            $fileName = pathinfo($fileNameWithExtension, PATHINFO_FILENAME);

            //Get file extension
            $fileExtension = $request->file('user_photo')->getClientOriginalExtension();

            $fileNameToStore = $fileName . '_' . time() . '.' . $fileExtension;

            //Upload image

            $imagePath = $request->file('user_photo')->storeAs('public/Employee_Images', $fileNameToStore);
        }

     
        
        //Saving User model Instance 
        
        $user->save();

    //getting all input using request all

        $input = $request->all();

        for ($i = 0; $i <= count($input['deduction_name']); $i++) {

            if (empty($input['deduction_name'][$i]) || !is_numeric($input['deduction_name'][$i])) continue;

            $data = [
                'allowance_id'=>$request->id,
                'user_id'=>$request->id,
                'deduction_value' => $input['deduction_value'][$i],
                'deduction_name' => $input['deduction_name'][$i]
            ];

            DeductionUser::create($data);
        }
        

        for ($i = 0; $i <= count($input['allowance_name']); $i++) {

            if (empty($input['allowance_name'][$i]) || !is_numeric($input['allowance_name'][$i])) continue;

            $data = [
                'allowance_value' => $input['allowance_value'][$i],
                'allowance_name' => $input['allowance_name'][$i]
            ];

            AllowanceUser::create($data);
        }

$account = new Account();
        $account->user_id = $request->id;
        $account->basic_salary = $request->input('basic_salary');
        $account->total_salary = $request->input('total_salary');
        $account->account_name = $request->input('account_name');
        $account->account_number = $request->input('account_number');
        $account->bank_name = $request->input('bank_name');
        $account->save();
