I entered the wrong amount on my w2 how do I change it?

[DanaB]

If you haven't filed yet then please see the following instructions on how to edit your entry: 

1. Login to your TurboTax Account 
2. Click "Take Me To My Return"
3. Click "Federal" from the left side of your screen
4. Scroll down and click "Start or Edit/Add" next to “Job (W2)"
5. On the "Here's your W-2 info" screen click "edit" next to the W-2 you want to correct

If your return has been already accepted by the IRS, you will have to file an amended return (1040X) to make corrections. The IRS will only accept amended returns via mail.

The 1040X form for 2018 isn’t ready. Please, keep checking the following information on how to amend your return; it will be updated once the 2018 form is released:
