Yes sorry. You need to buy the separate Business program (not the same as Home & Business) in addition to a personal version. Turbo Tax Business is not available to do online or on a Mac. You can buy the Window's version here. And you can have both TT Business and TT Home & Business (or any personal version) installed on your computer at the same time.

How have you been doing your C corp taxes? Is this the first year? If you haven't done a Business return before you should go to an accountant and get it set up right.
