If your return is already efiled and accepted, you will need to amend your return in order to add the additional W-2 information to your return. Amendment forms will be available mid February. Come back at that time and TurboTax will walk you through the steps of amending your return.
If your return is still in progress:
- Login to your TurboTax Online Account
- In your tax timeline, click Take Me To My Return
- Click Federal Taxes < Wages & Income < Edit/Add or Start (if you have not added a W2)
- Enter the appropriate information from the W2.
