1040-SR return was rejected . AGI didn't match what the IRS had. Return printed. Fix my return not available under the Tax Home screen. Why can't I go back and fix it?

Try entering 0 for the AGI. The IRS might have processed your return later so the AGI didn't get entered in time.  Especially if you mailed it.  That works for most people. See,

Be sure to attach copies of your W2s and any 1099s that have withholding on them.  You have to mail federal and state in separate envelopes because they go to different places.  Get a tracking number from the post office when you mail them for proof of filing.
