Received 1099-NEC as Trustee

I am the Trustee for my late grandmother's Revocable Trust.  I received a 1099-NEC as Trustee, as I do every year.  As the trustee I receive a payment to manage the trust as needed which include my time mostly, but also offsets cost needed to drive places, mail documents, postage etc.  When entering this 1099-NEC into TurboTax, I historically choose "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 choose the None of these apply to me, it wants me to create a Schedule C for a business.  Everything I have read indicates that my personal duties as Trustee do not constitute a business. 

Just looking for guidance/clarification/confirmation that choose "This is not money earned as an employee or self-employed individual, it is from a sporadic activity or hobby (this is not common)." for this is accurate.
