How does turbo tax calculate the tax after the adjusted gross income is determined?

It depends on what kind of income you have.  There are like 7 different ways to figure the tax.

See the IRS worksheet on 1040 page 36 for how the tax is figured.  Turbo Tax uses the same worksheet.

Even though it shows up as income on the first page,if you have capital gains or qualified dividends the tax on line 16 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 worksheets to see it.

Oh and the tax is not calculated on the AGI Adjusted Gross Income.  After the AGI on 1040 line 11a it subtracts your Standard Deduction or Itemized Deductions on 12e and other deductions on 13b to get the Taxable Income on line 15.   The Tax is on line 16.

Then you might have other credits, deductions and other taxes to get the Total Tax due on line 24.
