Delete that 1099-misc
Re-enter it this way:
Click Federal

Click “See All Income” if needed
Scroll down (PAST SELF-EMPLOYMENT) to “Other Common Income”
Click “Show more”
Scroll down to “Form 1099-MISC”
Click Start
Enter the 1099-MISC and Continue
On the “Describe the reason for this 1099-MISC” screen enter something like “referral gift” and Continue
Select “None of these apply” and Continue
Select “No, it didn’t involve work like main job” and continue through the interview selecting the appropriate answers for a one-time payment for the referral.
The amount from the 1099-MISC will be reported as Other income on the 1040 line 7a, not as Self-employment
