If you are the only owner and you did not elect other tax treatment at the time you formed your LLC, a single-member LLC is a disregarded entity for tax purposes and should file on Form 1040, Schedule C, just like a sole proprietorship.
The correct product choice for Schedule C filers is either TurboTax Self-Employed (online) or TurboTax Home & Business (Download/CD). [Please see the product comparison and purchase links below.] Either product will guide you through the full range of allowable business deductions. Both also link to Quick Employer Forms to allow you to create and e-file W-2s for your employees and Forms 1099-MISC for your vendors and contractors.
If your LLC has multiple owners and defaults to partnership tax treatment, or if you elected to be treated as an S Corp, TurboTax Business
(Windows Only) would be the correct product for filing the LLC's return.
