Sorry you have to report ALL your income no matter how small. Even $1 of bank interest.
That is self employment income. Even if you don't owe any income tax on your income you will still owe SE self employment tax. Self Employment tax (Scheduled SE) is automatically generated if a person has $400 or more of net profit from self-employment. You pay 15.3% SE tax on 92.35% of your Net Profit greater than $400. The 15.3% self employed SE Tax is to pay both the employer part and employee part of Social Security and Medicare. So you get social security credit for it when you retire.
