I have a mortgage over $750k so I can't fully deduct the mortgage interest I paid from my federal tax return. The TurboTax website acknowledges this fact in one of the screens, but then still deducts the full amount of mortgage interest paid.
Even when I manually correct the amount of deductible mortgage interest, it just ignores the number I enter and does not update the tax refund number at all (it should).
I also confirmed this bug by looking at the printable PDF of the tax return. The "Deductible Home Mortgage Interest Worksheet" does the correct calculation but it never uses the calculated number in any other forms.
