If you need to prepare a Form 1065 for a multi-member LLC, you will need TurboTax Business. TurboTax Business will generate both the business return and the K-1s needed for the members to report on their personal tax returns.
If you are a member of an LLC and have a K-1 to report on your personal tax return, you can use TurboTax Premier or Self-Employed/Home & Bus. (personal tax products).
