Is the AGI the total income you made? If so then is it true that I should enter that in as AGI

[VolvoGirl]

No.  The AGI is your Adjusted Gross Income.  It is only on your 1040 tax return.  Not your W2s.

You need your 2018 AGI to efile 2019. The AGI is on 2018 1040 line 7. If you filed a Joint return you use the same AGI for each spouse How to find the AGI.

The 2018 AGI is on the 2018 Federal tax return you filed Form 1040 Line 7
