It is because they now charge you to add these even if you are not self employed. They don't make it clear anywhere at all. It is a bit of a scam as far as I am concerned, many companies make their employees pay their own fuel expenses. But more frustrating is that you have to stumble around in TurboTax forever but will see no info on this. Last year I finally paid for the business version so I could add my wife's fuel expenses. She works for a company.
