The IRS is rejecting my federal and state returns by their error. What do I do?

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.
