High School Junior in non public placement. There was a work experience/job skills class where they went and did a job for a couple months during school.Where do I enter?

Child received a 1099-misc with an amount under $1000 in box 7. Class was during school hours only; a teacher drove them to class and stayed there during it, and drove them back. TT H&B wants to count child as sole proprietor. Not sure if that's correct, or where to enter information. Business income? Personal Income? Does it even matter? Do we even need to report this amount?
