You don't say who the payer is, the school or some other organization (a company).
The three choices: self employment, other income or scholarship.
If the employer was the school. it's scholarship. If someone else, one of the other, even if she got academic credit. You can use the one time gig exception to call it other income and avoid self employment tax. But other income is unearned income and her standard deduction is only $1150. She will have to pay tax. If it is taxable academic fellowship money, would it only be taxable IF her earned total income above the $12,950 filing threshold.
As you can tell, there's disagreement on this situation. That's my opinion. Tell us how you want to report it and we'll give you a work around in TT. Example at
