I have submitted using the 2018 AGI since I have only ever filed paper returns using TT, that is the only one they seem to have. My AGIs rarely vary much. Will see if it's rejected. If so, I will just courier the bloody thing to get the 2nd stim check as a refund.... some day. So getting the third will happen sometime late spring/summer perhaps as by THEN they will have my 2020? Fingers crossed again.
