The big orange button to e-file your return was in the FILE section. If you did not e-file your 2020 return, or if it was rejected and you did not notice, it is too late now to e-file it. A 2020 return cannot be e-filed. It has to be printed, signed, and mailed now.

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.
