Get your taxes done using TurboTax

A common issue is when the taxpayer has qualifying dividends or capital gains, because these are taxed differently than ordinary income. There is a worksheet for this called Qual Div/Cap Gn, which you can see in the desktop product by going into Forms mode (upper right) and looking for "Qual Div/Cap Gn" on the left.

There are a number of other tax calculations as well (considerably less common). Look on Line 16 on the 1040 - were any of the boxes checked? If so, then go to those forms for the tax calculation.

Where do you see the error? I ask because the tax appears to be calculated in a number of places, and it difficult to talk about this if we don't know which line you are concerned about.
