Self employed

Your business expenses must go on a Schedule C.   If you are using online TurboTax you need to use Premium.

If you have self-employment income for which you will pay self-employment tax for Social Security and Medicare,  you will need to use online Premium software or any version of the desktop software download so that you can prepare a Schedule C for your business expenses.
