Reasons attempts to e-file the federal tax return are rejected because of AGI.
1. Your 2019 return has not yet been processed. In this case, the IRS computer does not have an AGI for 2019. So tell the TurboTax program that you did not file a tax return for 2019, and the program will enter an AGI of $0 for you. (From my limited experience, entering $0 yourself is not enough. You need to actually tell the program that you did not file a 2019 tax return, and the program will enter an AGI of $0 for you.)
2. You amended your 2019 tax return, and the amended return changed your AGI. If you are presently using the AGI from the amended return, then try the AGI from the return before you amended it. If the other way around, then vice-versa.
3. Bottom line, the IRS computer just flat out has the wrong AGI in their system, and there's nothing you can do about it. So you have no choice but to print, sign and mail your return to the IRS.
4. Take note that after 5 (five) rejections the IRS computers flat out will not accept your e-filed return - even if the AGI and/or PIN are correct.
