For my mortgage interest deduction, Turbo tax fills out the Home Mortgage Interest Worksheet. The amount on line 22 of Part 3 of the worksheet shows an amount less than the mortgage interest that I paid. It says that this should be reported on Schedule A line 8a. The number is the same as what I calculated based on IRS publication 936. However, on Schedule A line 8a, TurboTax still shows the total amount paid rather than the reduced amount on line 22 of the worksheet. It appears that there is an error in Turbo Tax.
