Even though you did not receive a 1099-MISC nor have any business expenses to deduct, you will still need to report this as self-employment income.
If you did not set up a separate company related to this income that requires a business income tax return, you will be able to report this income on your personal tax return as self-employment income. (This includes a single-member LLC which is a disregard entity for Federal income tax purposes and is reported on a Schedule C attached to your personal tax return).
If you are using TurboTax Home and Business (Desktop version), you will report this income under the Business tab>business income and expenses (Screenshot #1)
If you are using TurboTax Self-Employed (Online version), you will enter the information under "Federal Taxes" >Income and Wages>Check for more income>see all income>Self-employment (Screenshot #2)
