You can obtain a transcript of your tax return which will likely show the difference between what the IRS calculated and what TurboTax calculated. Compare the items that you reported with the "PER COMPUTER" items with the same name that immediately follow; "PER COMPUTER" items are the results of the calculations done by the IRS.

Note that the IRS sometimes rounds differently than does TurboTax and even a $1 difference can sometimes move you to an adjacent line in the tax table. Moving one line lower in the tax table could explain the $10 difference.
