Babysitting Income
Menu Path: Income > Business / Rental Income > Business Income (Schedule C)
If the babysitting is not a job where you get a W-2, then you would enter the babysitting income on the Business Income (Schedule C) screen. You can leave most of the business income questions and screens blank, but that is where you would enter the income. The babysitting income will then show on Schedule C and be subject to self-employment taxes.
