The IRS requires your 2018 AGI to verify your identity for e-filing. If you're paper-filing your return, you won't need your AGI because those are manually processed.

There are a few places you can get your 2018 AGI:

• If you filed your 2018 taxes with TurboTax, sign in and go down to Your tax returns & documents. Select View adjusted gross income (AGI).
• If you didn’t file your taxes with TurboTax in 2018, the best place to get last year's AGI is from the 1040 form you filed with the IRS. Look on page 2, line 7. If you filed a 1040NR, it'll be on line 35.
• If you're having trouble locating your 2018 return, the second-best place to get your AGI is from the IRS. You can order a free transcript of your return at the IRS Get Transcript site or you can purchase a full copy of your 2018 return. Both versions will include your AGI.

If you didn't file a 2018 federal tax return (or you haven't filed one yet), enter 0 as your AGI.

Is it updating?

This happens very often.

another user on this forum, whose User ID I've forgotten, has demonstrated that there is a TurboTax problem.

If you really want to e-File, use another software package.

Otherwise, file on paper via US Mail.

Good info; however, the answer does not directly address the technical question.
