Help: This is not money earned as an employee or self-employed individual, it is from a sporadic activity or hobby (this is not common).

I'm trying to figure out how to answer this question:

"Does one of these uncommon situations apply?

...

This is not money earned as an employee or self-employed individual, it is from a sporadic activity or hobby (this is not common).

I am a professional who was invited to a conference to run a workshop for a day.  This is a one off event.  My hotel and conference registration was paid for by the conference, but I was also given a $900 honorarium and was issued a 1099-NEC.  Am I supposed to check the above box since this is a sporadic activity?

Thanks.
