As Champ @ Mike9241 mentioned above, you should also look at the Qualified Dividends and Capital Gains Tax Worksheet to see the actual calculation in detail. That worksheet breaks down the calculation by each of the capital gain rate brackets, and you can see how much of it is taxed at each capital gain rate bracket.
You have not mentioned that you looked at that worksheet.
Are you using desktop software (CD/download?) If so, then go into Forms Mode, and you can find that worksheet in the left column list of forms. In the forms list it is abbreviated as "Qual Div/Cap Gn".
If you're using Online TurboTax, we can tell you how to get it.
