Invalid Format Access Denied Public Key Laravel Forge

Hello, I am trying to ssh into my application from the command line however I am having issue with the ssh public key.

1st => I tried using PUTTTY to generate keys and save with appropriate name and extension id_rsa.pub which seem to work great

2nd => I ran this command ~/.ssh/id_rsa.pub to copy key and place it in the ssh key option on the laravel forge dashboard

3rd => I ran ssh forge@my_id_address and it threw an alarm saying public key access denied

So then I found this website Click Here and followed the steps using the Git Bash command line to generate keys

The command ssh-keygen -t rsa -C "[email protected]" which worked to generate keys however I was unable to create passphrase??

Next I pasted the public key in the laravel forge dashboard

And then I used ssh forge@my-ip-address -i ~/.ssh/your-key as suggested and got the following alarm

Load key "/c/Users/username/.ssh/id_rsa.pub": invalid format
forge@my_ip_address: Permission denied (publickey).

I have seen this as a common issue I guess but no luck with suggested fixes, any help would be greatly appreciated!!!
