If Your self-employment income was only from cash or personal checks or credit card payments, follow these steps:

Type “Schedule C” in the Search box (upper right of program) and then select the “Jump to” link from results. This will take you to where you can enter any cash, personal checks or credit card payments (Form 1099-K) related to your self-employment. You may be asked some general questions about your business. After you answer them, you’ll be taken to the Your Business screen where you can enter this income as Additional Income under Business Income.
