If you need to file an income tax return for a partnership/multi-member LLC (Form 1065), S corporation (Form 1120-S), C corporation (Form 1120), or trust/estate (Form 1041), then you need TurboTax Business (link below).
Note that TurboTax Business is not available Online, but must be installed and run in a Windows environment (there is no Mac version). Further, TurboTax Business can only be used to prepare returns for entities (see above); the program cannot be used to prepare your individual income tax return, for which you need a separate TurboTax product.
