After you file

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)?
