If you are the only member, you can file a Schedule C with your Form 1040. You only need TurboTax Self-Employed to file your business and personal returns together.
If the LLC has multiple members, you will need TurboTax Business to file your business return. The business return will generate K-1 forms that you will use to complete your personal tax return. You will need TurboTax Premier or Self-Employed to file your personal return with a K-1. So, you need two programs if your LLC is multi-member.
