TurboTax calculated the sales tax that I can deduct using the tax tables. Then I went back and Revisited the Sales Tax deduction to add the taxes paid on a remodeling project. Turbotax wouldn't let me enter it via the interview, but I found my way to the "Tax and Interest Deduction Worksheet" and entered the numbers there. Never-the-less, TurboTax ignores the additional number in the totals. The IRS website Tax Deduction Calculator does include the additional taxes paid and adds that number to the value that TurboTax insists on. Looks like a bug in TurboTax.
I posted that note to the TurboTax support community on January 31 but so far no replies.
