I did the e-file last week and then got rejected due to potential issue on 1116 foreign tax credit carryover calculation. Then I did the update on 3/18, and e-file again. But now got rejected because of "AGI or self-select PIN doesn't match IRS record". I went back to my 2020 tax return and double check with those numbers and are 100% sure the numbers are correct. Tried several times of e-filing again, but same results.
Could it because I did paper filing last year (TT didn't fix 1116 form problem last year and I was forced to do paper filing) and maybe somehow the IRS stuff mistakenly input my AGI number differently? I did some research and found that you could request a digital copy of your last year's return. The process requires a online Video Authentication, but since I live in China now and the Firewall between China and the US make it impossible to register a online account with IRS.
Can anyone advice on this problem? If I call IRS directly, can they verify my AGI over the phone? Or is there any other way to e-file my tax return. Don't want to end up with paper filing again like last year.
