Help Line 16 on my 1040 (tax year 2024) is being calculated incorrectly. How do I contact support to fix it, or do I have to manually file by mail to override it?

I have triple checked the amounts. See for yourself on the tax tables: https://www.irs.gov/pub/irs-pdf/i1040tt.pdf Filing married jointly. My line 15 taxable income was over 99,000 and my tax owed on line 16 was only 11,050. You can see in the tax table that the lowest amount it could possibly be is 11,892. I do not feel comfortable filing this because it is very wrong.

There is more than one tax table.  Did you ----- for example -----enter any capital gains or qualified dividends?

There are like 7 different ways to calculate the tax.
It's very common for the tax to be less than you can figure using the IRS tables. It depends what kind of income you have. Even though the full amount shows up in the total income on the 1040 line 7, if you have capital gains or qualified dividends the tax is not taken from the tax table but is calculated separately from Schedule D. The tax will be calculated on the Qualified Dividends and Capital Gain Tax Worksheet. It does not get filed with your return. In the online version you need to save your return as a pdf file and include all the worksheets to see it.

For the Desktop version you can switch to Forms Mode and open the worksheet to see it. Click Forms in the upper right (upper left for Mac) and look through the list and open the Qualified Dividends and Capital Gain Tax Worksheet.

IRS Qualified Dividends and Capital Gain Tax Worksheet—Line 16 on 1040 instructions page 37

And you might need IRS Tax Table page 15 to calculate the tax and to compare to Turbo Tax. That isn't shown in Turbo Tax.

Thank you for your quick response. I will look into these schedules and see if they address the problem.

Thanks, the problem was in fact that Turbo Tax online edition does not include the Qualified Dividends and Capital Gains Tax Worksheet in the downloadable PDF. I do not see the option to "include all worksheets." So I completed the worksheet myself and the amount correlated to the value in line 16.

Thank you for your help.
