This income is considered "Income from Self-Employment". If your net income from this activity (income minus expenses) was less than $400, you may enter it under "Income & Wages " as "Miscellaneous Income"/"Other Reportable Income".
If your net income from this activity is more than $400, you will need to report it on Schedule C of your return by entering it under "Wages & Income" / "Self-employment income and expenses".
