If the LLC is a Corporation then it files a Form 1120 income tax return. If the LLC is a Partnership then it files a Form 1065 income tax return.
Corporation or Partnership tax returns can only be created, completed and filed using the TurboTax Business Edition. The Business Edition can only be installed on a Windows base personal computer, not on a Mac or online. The Business Edition cannot complete a personal tax return - https://turbotax.intuit.com/small-business-taxes/
The Corporation or Partnership issues you a Schedule K-1 for your share of the income, deductions, etc. The Schedule K-1 is entered on your personal tax return.
Using the TurboTax online editions you would need either the Premier or Self-Employed editions for entry of the Schedule K-1 - https://turbotax.intuit.com/personal-taxes/online/
