Ideally your employer should give you a corrected W-2. If they can't or won't, then do this:
Enter your 1099-MISC in the Other Common Income section of TurboTax, on the line for 1099-MISC. Go through the follow-up questions. You'll come to the page that says "Does one of these uncommon situations apply?" Check the response "My employer reported this extra money on a 1099-MISC but it should have been reported on a W-2". Then proceed through the rest of the questions.
**Answers are correct to the best of my ability but do not constitute tax or legal advice.
