Employer withheld too much Medicare tax

When you enter your W-2, TurboTax automatically calculates what your Social Security and Medicare withholding should have been (6.2%). If the amount actually withheld is more than this amount, TurboTax will prompt you to double check your entries.  

If your employer did withhold too much, they owe the difference to you.

Here's what to do next:

1. Contact your employer to get a refund of your overpayment of Social Security tax.
2. Let them know you need a corrected W-2
3. Once you receive this new W-2, you'll need to update the amounts in TurboTax
