Here's the background. I filed TY2023 taxes on extension, with paper.
I electronically filed for TY2024 using the TurboTax TY2023 AGI. This got rejected.
I looked at my filed PDF for TY2023 and verified that the AGI was correct.
I got my TY2023 transcript from irs.gov. It verified that the AGI was correct.
Electronically filed again, with no AGI changes. rejected.
Called an IRS agent, and she said that even though I could read the transcript, the IRS couldn't use that because the filing was later than normal. (Why does it not surprise me that the left hand does not know what the right hand is doing!?)
So I electronically filed again, with an AGI of 0. rejected.
Called another IRS agent on the following day. She gave me this one weird trick: Use AGI of 0.00 instead of 0.
So AGI of 0.00? accepted.
