If you did not file your 2017 return, then there is no 2017 AGI in the system for you. Try using zero and you might be able to e-file your 2018 return. If zero will not work then you have to print, sign and mail your 2018 return.
Meanwhile, if you did not end up filing your 2017 return after it was rejected, by printing and mailing it in, that is what you still need to do to get it filed.
Online preparation and e-filing for 2017 is permanently closed. You have to download 2017 software to a full PC or Mac (not to a mobile device) and then print, sign and mail your return. If you already paid for your TurboTax software, you can contact customer support to push a download of the software to you.

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 and/or your state received the return.
