It just occurred to me---- if you are trying to use the 2018 AGI on that unfiled 2018 return so that you can e-file 2019, it will not work since it never made it into the system.
For your 2018 AGI try using zero, but if zero does not work, you will have to print, sign and mail 2019.
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.
