If you are trying to prepare and file a Form 1065 for a partnership or multi-member LLC, then you need TurboTax Business to do so.
See https://turbotax.intuit.com/small-business-taxes/
TurboTax Business can only be used to prepare income tax returns for entities and is not available online nor is there a Mac version; the program must be installed and run in a Windows environment.
If this is your first year preparing a Form 1065, professional guidance is recommended. Also, note that Form 1065 was due March 16th and, thus, it would be considered late at this point; there are penalties for late filing.
