Your W-2 has nothing to do with your AGI in any way, form or fashion. AGI is your *ADJUSTED* gross income which will never be the same as reported in box 1 of any W-2. get the AGI from line 37 of your 2017 form 1040

How do i get ahold of my 1040 I dont ever remember getting one.

If you did not file a 2017 tax return then enter a 0 (zero) for the 2017 AGI.  Otherwise use the procedure as shown in the TurboTax support FAQ link in the answer below.

Form 1040 is the income tax return that you filed.

Your 2017 AGI is not from a W-2.  It is on your 2017 tax return.
