I just got nailed for a $7,000 tax error in the IRS's favor because of a TurboTax flaw in my return. It incorrectly calculated the tax on my and my wife's social security income. The tax it calculated on my social security income was only a third of the correct amount. This was a painful error in the software. For what is charged for the software, this is inexcusable. Because of my RMDs, I am in a very high tax bracket, and any error like this can be financially painful.
