Intuit's category scheme is exceptionally user-friendly: Instead of simply repeating the list of allowable expense types from the IRS form, Intuit uses its own list that relates to how businesses work. For example, TurboTax Home & Business has a category called Communications that covers everything you might expect it to, including landline phone and Internet service. These items may end up in different places on Schedule C, but having them together when you go through the program avoids a lot of confusion, especially for newbies.
