To clarify - I didn't efile my 2020 return last year but mailed it with a check before the tax filing deadline last year. I am efiling this year. Are you saying they don't have my 2020 AGI in their database though I mailed my return, or is it that they don't have the 2020 AGI in the database because I did not efile last year (only mailed it)?
The IRS will cash checks when they receive them; it's no indication of any return having finished processing. Processing for a mailed 2020 return can take several months due to the Pandemic at that time and the huge backlog. The IRS was terribly behind on mailed 2020 returns, and actually is still processing some 2020 returns.
Since you tried using the 2020 AGI from your original 2020 return (not an amended one, if any), then the next step is to try using a 2020 AGI of 0 (zero.)
