TurboTax doesn't always use the Tax Tables or the simple Tax Computation Worksheet (for higher incomes). It uses whatever is required by the circumstances in your return, which sometimes involves other computation forms. For instance, as one of the more common examples, do you happen to have any qualified dividends and/or capital gains? If so, the tax is figured on the Qualified Dividends and Capital Gain Tax Worksheet.
Tell us if you are using Online TurboTax or desktop TurboTax, and I can tell you how to look at the Tax Smart Worksheet that shows what method(s) TurboTax used to calculate your tax.
