Sales tax deduction in Turbotax 2025 not working properly when entering 'major purchases'

[Ron7996]

When you select "major items" for sales tax deduction, the software lets you enter these but then does not provide the sales tax from the IRS table.  The total sales tax deduction (as per the IRS guidelines) should be the total for major items PLUS the figure from the IRS table for your location (zip code).

After you enter the sales tax on a major item you get a screen with the heading "Major purchases results." The last line of that screen says "Deduction allowed" and shows the total amount of the sales tax on the major item. But the wording is confusing. The amount it shows as "Deduction allowed" is not your total deduction. It's only the amount allowed for that major item. The total deduction for state sales tax on Schedule A line 5a in your tax return does include the amount from the IRS table in addition to the tax on the major item.
