Get your taxes done using TurboTax

If you decide to treat this as self-employment, then you need to upgrade to Premium, because you need to create a schedule C for the business.  You don't enter the 1099-K and value of other items as personal income, you enter them as business income.  You create the business in the program, which gives you a schedule C.  You answer some basic questions about the business, then you enter your business income.  There is a place to enter income that is reported on a form, and there is a place to report cash or barter income that is not on a form.
