1099-NEC Does this fall under, "sporadic activity or hobby"

My wife decided to try selling Monat products from the company Monat Global. She got commission doing so for a couple months but decided it wasn't for her. She made enough to get a 1099 NEC from the company. I am confused on how to fill this out.

 

After filling out the 1099 NEC info on TurboTax asks, "Does one of these uncommon situations apply?" One of the options being, "This is not money earned as an employee or self-employed individual, it is from a sporadic activity or hobby (this is not common)." If I select this, then my tax return dollar amount goes down, and then that is it for the section.  Otherwise the, "None of these apply to me" would be the next best option, which tells me a Schedule C is necessary.

 

Because my wife just did this on a whim, and doesn't have a business or anything, can I consider this a sporadic activity or hobby? Or will she need to still fill out a schedule C? If she doesn't have a business or anything, then how would she fill out the schedule C?
