I think I entered my federal adjusted gross income wrong

There's nothing to worry about. The AGI is currently being used to verify peoples identity for Efiles. If you enter the wrong AGI the Efile will be rejected right away. It is impossable for the wrong AGI to get accepted, so if you entered the wrong number you will get an email about it very soon. If this happens follow the steps below.

Sign back in to your TurboTax account. You will see a message that is asking you to fix your return. Click on that and go through the steps, it will have you attempt to file again.

Make sure you have the right number this time. Fixing it is very quick and easy, but if you send the wrong number too many times you won't be able to Efile this year. I'll post some information about the AGI to help you understand where it is and how to get it.
