Retirement tax questions

I hear what you're saying.

 

When I amend my e-file (assuming the IRS rejects my original 2020 e-file), I'm wondering how I should input the information that I have already received $3600 in 2020-2021 from the stimulas program?

Should I enter ($1200.00) in Box 30?

Or  - (minus) $1200.00 in Box 30?

 

Since entering that information is based on a Yes or No answer to Turbotax's questions, how and when can I enter the correct dollar amount to Line 30?

 

Since you said that I can keep the extra $1200 Turbotax told the IRS to send me, when I do my 2021 taxes, what would you suggest I do to return the government's money ($1200? $2400?) to them?

 

Thanks for your input, I really appreciate it.
