If you have a multi-member LLC (as it appears) without an election to be treated as a corporation for federal income tax purposes and are not officially married and reside in a community property state, then you are required to file Form 1065.
Form 1065 is only available in TurboTax Business (link below) and the program must be installed and run in a Windows environment (there is no Mac or online version).
