But the deduction on Schedule A is limited to $50 a month, right?  And it's really not rent if it covers food, transportation and other expenses.  Not everything on a 1099-NEC is subject to SE tax, but I agree that the knee-jerk IRS computers might see it that way if there is enough money involved.  Like, more than $3,500 or so to generate at least $500 assessment.  

Where does the paying organization get its funds?  Do the students pay to be in the program?  Beginning to sound more like a business.  I wouldn't rule out Schedule C, but we really don't have enough facts and circumstances.
