You should report all of the income you receive, but it depends what you did to earn this income. If you did any work to receive this income then it's self-employment income, which is most common. They don't have to file you a form 1099-misc for you to report it.
When you have self-employed income, you'll need to setup your business in the software. Self-employed income is considered a business, even if you didn't think about it that way, so don't be alarmed by the label. To add your self-employed business, follow the steps below:
1. Log in and click Take me to my return
2. Click Federal Taxes and then Income & Expenses (If you have the blue button 'Check for more income', click it and then click 'Skip to see all income')
3. Next scroll down to Self-Employment and click Show more
4. Click Start/Revisit next Income & Expenses
5. Next, you'll be able to enter your business info. You can just enter your personal name for your business name and answer the questions accordingly.
If you earned the money for another reason, please let me know.
