This is so frustrating. I've tried to e-file at least 6 or 7 times and continue to get the same error. I even input zeros as someone suggested. I've logged into my IRS account and have verified my AGI is the same as the one they have for 2020, but to no avail. I've even paid to transmit my state return, but if I can't get the federal e-file completed, I can't e-file my state income tax. This is just super frustrating. Hope someone has an answer.
