Do you need to do the Estate tax return?
If you need to file a separate Business return like for a 1065 Partnership or LLC or a 1120 including a Single Member LLC - S corp or a 1041 Estate/Trust return you need Turbo Tax Business.
Turbo Tax Business is not available to do online or on a Mac. You can buy the Window 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.
