It seems that you've entered something that makes TurboTax think that your Medicare wages are above the threshold. There are no user-entered fields on this form, so its only reason for being present would be because of an incorrectly entered amount in box 5 of TurboTax's W-2 form. Go back and check your W-2 entries for a missing decimal point. If you correct that entry, TurboTax will automatically remove the unneeded Form 8959.
