No, it isn't business income. It's a one-time payment so you can enter it as "Other Income" instead of self-employment income. Follow the navigation instructions in the TurboTax Help article Where do I enter a 1099-MISC?
Your income will appear on line 8 of Schedule 1 of your 1040 as Other Income.
Refer to the TurboTax Help article What's the difference between self-employment income and other income? for more information.
@SharonD007You are AWESOME! It worked and it was taxed at a lower rate. I would have never figured this out on my own! Thank you!
