You can use either. A single member LLC is disregarded for income tax purposes, so you report it as self-employment income (business income) on Schedule C. In TurboTax Online, any edition will allow you to enter a 1099-MISC and have the income reported on Schedule C. But if you have income that is not on a 1099-MISC, or you have business expenses, you have to use Self-Employed. If you use the CD or download TurboTax software you can use any edition, but Home & Business will give you a more detailed interview and more guidance for self-employment.
