Hi, I filed my 2020 paper return last year and got a letter from them today that they don't have it and want me to resend it. I know they do have it because I had to pay and I sent the check with the returns and they deposited the check So I know there's a significant delay on paper processing so I want to file online this year.
Will I have an issue if I do since they still haven't processed my 2020 returns?
