You will report your income and expenses on Schedule C for self-employment.

You can prepare your tax return including this form in either TurboTax Self-Employed (online) or TurboTax Home & Business (CD/download).

You will list the information about your business, then the income, finally the expenses. 

The program will walk you through everything.
