Thank you for your response @DianeW777
The overpayment only occurred in 2020. The overpayment issue was the result of a miscalculation in my compensation during the weeks I was unemployed during the pandemic. After I called to double check, since my employer had taken out one of the PPP loans, they stated the amount I was paid would have to be returned and they would send a corrected amount to me for those same weeks and then close my account so I wouldn't keep receiving compensation when it wasn't necessary and thankful no other compensation, besides the corrected amount, was received.
Given all the information in your comment. I'll need to just keep my 2020 tax return around, since the overpayment and the corrected amount I received only occurred in 2020. I'll probably keep my 2021 tax return around just in case. Other wise I'll just file my 2021 tax return like normal and prepare to correct the issue next year on my 2022 taxes.
