1099-NEC but not self employed

My wife is a preschool teaching assistant.  The school participated in a program called Iowa Wages which you apply to receive additional compensation.  It's meant to be promote people in these jobs.  The extra compensation turned out to be about $900 and she just received a 1099-NEC.  As I read it, the 1099-NEC reports money as if you own your own business or are a contract worker. It may even require us to make estimated quarterly tax payments.  She is not self employed nor an independent contractor.  I don't know how to treat this in TurboTax.  Any help would be appreciated.
