You have self-employment income in addition to your W-2 job, so you will need to use either any version of the desktop software or Self-Employed if you use online TurboTax. You have to prepare a Schedule C for the self-employment income expenses---which can be done using desktop SW or Self-Employed. You will pay self-employment tax for Medicare and Social Security as well as ordinary income tax.
