I e-filed my return and it was accepted by the IRS, but I received a new W-2. How do I change my tax return?
To change your return after the IRS has already accepted it, you'll need to do an amended return, Form 1040-X. Sign in to your account and click the Amend Tax Return link from the Account menu in the top right. We'll help you to prepare your Form 1040-X amended tax return.
We recommend that you do not amend your tax return until after you have received your refund or paid the taxes you owe from your original return you filed. The IRS will often automatically make a correction to your tax return for missing or incorrect W-2 or 1099 forms. You do not need to amend your federal tax return if the IRS corrects the error when they process your original tax return. You will receive an IRS notice explaining the adjustment or asking for additional forms for documentation.
