Depends what kind of LLC you have. Are they Single Member LLC? You will need the Online Premium version or any Desktop program for your personal return. You may also need the separate Desktop Business program which is only available for Windows to do the LLC returns.
The small business program (TT Business) is for 1120 Corporation, 1120S Corp, 1065 Partnership or 1041 Estate/Trust returns and will not do your personal 1040 return. It is a separate program from the Desktop Home & Business program.
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.
