Let's start out with the LLC with a partner. If you are going to do the tax return for the LLC, you will need TurboTax Business, whether you file as a partnership using form 1065 (the IRS default) or an S-Corp on Form 1120-S (if you made that election). TurboTax Business is a PC desktop product (won't run on a Mac) that installs on your computer either by download or CD install. If you are going to use TurboTax Business then I recommend you use TurboTax Desktop for your personal returns. If you have a state return to file, I suggest you start in Deluxe, you can upgrade from within the program if you find it necessary.
