That's not the tax table. The tax table is 12 pages in the IRS Instructions for Form 1040 and 1040-SR, pages 64 - 75. When you use the tax table you just look up the amount of tax in the table, based on your filing status and small ranges of taxable income, in increments of $50. It does not involve any calculation or percentages.
But the tax table is only one of seven different methods that can be used to calculate the tax, depending on what is in your tax return. Your tax return must require one of the other methods. The most common reason that you cannot use the tax table is that your income includes qualified dividends or long-term capital gains, which are taxed at lower rates. If you do have qualified dividends or long-term capital gains, your tax is probably calculated on the Qualified Dividends and Capital Gain Tax Worksheet, or possibly the Schedule D Tax Worksheet.
In the IRS Instructions for Form 1040, look at the instructions for line 16. Starting in the right column on page 33 it explains the conditions for determining which of the 7 methods to use to calculate the tax.
You can see which method TurboTax used by looking at the 7 checkboxes in the Tax Smart Worksheet. The Tax Smart Worksheet is between lines 15 and 16 in the first section of the Form 1040 or Form 1040-SR Worksheet.
