The IRS has rejected my federal and state returns because it says the AGI I entered for the previous year (2019) is wrong. However, it is correct. Not only is it directly from the form I filed, but when I call the IRS hotline, it confirms the number. What can I do, since this is some sort of IRS error? Their phones are too busy and I cannot reach a human. They do not put you on hold or take messages.
You can also obtain an Identity Protection PIN (IP PIN). You may be able to e-file using that. To obtain one, go to: Get An Identity Protection PIN (IP PIN)
If that doesn't work, you will have to print and mail your returns.
