You need to buy Turbo Tax Business, not to be confused with the personal Home & Business version. Home & Business is just for personal returns that need schedule C for self employment. TT Business is not available to do online or on a Mac. You can buy prior year Business programs here (last one on the right). You will need a full Windows computer to install it on.
