You have self-employment income and will need to use any version of the CD/download or online Premium in order to complete a Schedule C for your business expenses.
If your self-employment income was only from cash, personal checks, credit card payments, or cryptocurrency
Type Schedule C in the Search box and then select the Jump to link. This will take you to where you can enter any cash, personal checks, credit card payments, or cryptocurrency (Form 1099-K) related to your self-employment. You may first be asked some general questions about your business. After you answer them, you’ll be taken to the Let's get income for (your line of work) screen where you can enter this income as Additional Income.

You may deduct legitimate business expenses if you kept records, and you pay income tax and self-employment tax on the net profit.
