Worked as a hair stylist. What form do i use?

If you worked as a hair stylist and received a W-2, you are an employee and can use any version of TurboTax.  But if you ran your own business, you were self-employed and you will report your income and expenses on Schedule C.  It looks like you are using TurboTax Self-Employed which is the version you need for self-employment.  See below for instructions on how to set-up/enter your Schedule C.  After you have your business profile set-up, you can enter any income and related expenses to determine your gross profit which will be transferred to your Form 1040 tax return.  

Where do I enter Schedule C?  In TurboTax, it can be found under Self-Employment income and expenses..
