You will need either TurboTax Self-Employed (online) or TurboTax Home & Business (desktop/download). This assumes you didn't take any steps to be taxed as an S-Corporation but will file a Schedule C for your self-employment. TurboTax Home & Business will also allow you to view your tax forms as you prepare your return and it provides a little more assistance.
