. . . and add $217 of additional medicare tax on form 1040 Line 25C.
Form 1040 line 25c is not additional tax that she is paying. It's the Additional Medicare Tax that was withheld on her W-2. Putting it on Form 1040 line 25c is how she gets credit for the Additional Medicare Tax that was withheld. The amount on Form 1040 line 25c comes from Form 8959 line 24. It ends up getting subtracted from her total tax, not added.
I have attached below a PDF of what I think her Form 8959 should look like, based on the information you have provided, and assuming that she has no other W-2 and no other income subject to Medicare tax or self-employment tax. Schedule 2 line 11 should be $216 and Form 1040 line 25c should be $217. (The difference between $216 and $217 is due to rounding.) If this is what you have on her forms, the calculations are correct. If this is not what you have, what specific lines are different, and what are the amounts that TurboTax shows on those lines?
If you have additional questions about the calculations, please provide specific form and line numbers and amounts, not just "TurboTax calculates. . . ." Indicate the amount that TurboTax calculated, what you think it should be, and how you arrived at your amount. Also please tell us whether you are using TurboTax Online or the CD/Download TurboTax software.
Who is "her"? What is her filing status? It appears to be either Single, Head of Household, or Qualifying Widow.
