I've completed entering my information into TurboTax and was expecting to have an additional medicare tax liability but it was not included in the amount calculated and therefore I'm wondering whether I misunderstood the requirement or there is a glitch in the system, which I realize is incredibly unlikely. On Form 8959, line 1, I have $265,978, which is the sum of the amounts from my and my spouse's W2 box 5 Medicare wages and tips ($199,567+$66,411). Since both are under $200,000, the extra medicare tax was not withheld. Lines 2, 3, and 4 are $0. I'm filing joint, so line 5 is $250,000 and line 6 is $265,978 - 250,000= 15,978. In Line 7 I multiply that by 0.009 to get an additional medicare tax of $144. In my draft TurboTax return, that $144 is not included in my total liability. I uploaded the W2s so that amounts in box 5 are definitely in the data I submitted. Do I not really owe this or how can I get the TurboTax to recalculate?
