If you filed a joint return the previous year then the AGI is the same for each spouse. It is on line 8b of your 2019 Form 1040. When you are on the screens in the software to enter the AGI to e-file for 2020 you literally type the same number two times---once for each spouse---in order to e-file. It is not a bug.
However, if you filed 2019 late or amended, the IRS might not have your 2019 in the database to match up with your SSN's anyway, and you have to try using zero when that happens. If neither the AGI nor zero will work to let you e-file then print, sign and mail your return.
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.
And make a note of your 2020 AGI which is on line 11 of your 2020 Form 1040---that is what you will need for each spouse when you want to e-file 2021.
