Trying to file, and it keeps rejecting. Both the AGI and the PIN are correct. I'm still waiting for my refund from last year, they say millions of people still haven't had their returns processed from 2020. I just followed advice from another post and entered zero for the AGI, apparently if last years return isn't shown as completed in the system it doesn't recognize what's actually the correct number. TurboTax support says the following - If you printed and mailed your return and it was not processed by December 10, 2021, then enter “0” for your 2020 AGI. But it still didn't go through.
