You will need to report this as self-employment income and report the income and expenses on Schedule C, assuming you are a sole proprietor.

 

From the Federal menu, click on Wages & Income (Income & Expenses if you are already using TurboTax Self-Employed). Expand the menu for Self-Employment. Click Start/Revisit next to Self-employment income and expenses. You will enter the information related to the business and include income and expenses in the categories as needed. Some information related to deducting business expenses is found in the links below.
