No matter why the return was rejected, it is now too late to e-file it. The only way to file a 2023 return is by mail. You are going to have to print it, sign and date it in ink, and mail it to the IRS and state.
If the rejection was for AGI, AGI does not matter when you mail a tax return, so you do not have to try and fix that. If something else was wrong, and you have to make any sort of change to the return, you will need to use the desktop software which has to be downloaded to a full PC or Mac.

If you are getting a refund, there is no penalty for filing late. If you owe tax due, then file and pay the amount due as shown on the Form 1040, but expect a bill later from the IRS for the penalty and interest you will owe. Only the IRS will calculate this—TurboTax will not calculate it.
When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s. Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS/state received the return.
Federal and state returns must be in separate envelopes and they are mailed to different addresses. Read the mailing instructions that print with your tax return carefully so you mail them to the right addresses.
