I was a soccer ref, got paid thru association. They sent a 1099K. I can't find proper form. This was not crypto paid.

Surprising to hear you were issued Form 1099-K as that form is for third party payers, such as PayPal. 

 

You can enter the 1099-K under 

Income

Other Common Income

Income from Form 1099-K

 

Select "Hobby income" or "Self-Employment income" (depending how you treat it) from the list on the "Which type of income is your 1099-K for?" screen.
