You report it as "other income" on Schedule 1 line 8. Here's how to enter it in TurboTax.
In the Search box type "lawsuit settlement" (without the quotes), then click the link that says "Jump to lawsuit settlement." I know that's not what you have, but it's the only search term I could find that gets you to the right place.
The first screen asks, "Any Other Taxable Income?" Click Yes.
On the next screen, "Other Taxable Income," enter a short description such as "Surveys" and enter the total amount. Click Continue.
On the next screen click Done.
The income will be reported on Schedule 1 line 8 with the description that you entered.
