After you file

First, please be a bit nicer.  All of us are trying to help you.  And the return is not before us, on our computer, where we would have a more complete idea of what you have and why it is not working.  If these are the facts:

you filed 2020 and 2021 the same way, MFJ.  For both years, your name and your SS# is on Top.  

Therefore, it is reasonable that when the IRS computers check for 2020 AGI, they would get the number you entered for 2021.

Please work with us to solve your problem, together.
