You can file your tax return with a Substitute W-2, Form 4852. On the screen in TurboTax where you enter your W-2 information, enter the correct information, not the incorrect information that is on your W-2. After you click Continue on the W-2 entry screen, you will get a screen that says "Do any of these uncommon situations apply to this W-2?" (There might be some other questions about your W-2 information before you get to this screen.) One of the boxes says "Substitute form - I didn't get a W-2 from my employer and need to complete a substitute form." Put a check in that box (even though that's not exactly your situation) and click Continue. The next screen asks if you want to complete Form 4852. Click Yes. Proceed through the screens, entering the requested information to complete Form 4852.
