If your return is rejecting for incorrect AGI, you can get a copy of your return from the IRS to see what they have on file. If for some reason you still can't get your return to go through, you can still file, you will just need to mail in a paper return.

See the TurboTax FAQ below on how to find your AGI on your form:
To e-file your 2017 taxes, the IRS requires your 2016 AGI for identity verification (unless you didn't file 2016 taxes; in that case enter 0 as your AGI).
As long as you transfer last year's taxes over to your 2017 tax return, we'll also transfer your 2016 AGI behind the scenes.
But if your 2016 AGI didn't transfer – for example, you created a new login for 2017, your 2016 tax return is on your old computer, etc. – read on.
Where to find your 2016 AGI
The best place to get this number is from your originally-filed 2016 federal tax return.
Even if you amended it later, you must use the AGI from the 2016 return you originally filed, even if it's way off. Choose the 1040 variant you filed last year (below) to see which line shows your 2016 AGI.
Don't have a copy of last year's return? You can order a transcript from the IRS. Go to their Get Transcript site, choose Get Transcript Online, and follow the directions (if you don't already have an account, you'll need to set one up).
One thing's for sure – you won't find your 2016 AGI on last year's W-2 or 1099 form. More info
