My wife received a grant to write the digital edition of an open textbook. She didn't have any expense and this was in addition to her regular salary. She received a regular W-2 from her employer as an assistant professor, and a 1095-NEC from another college which has a partnership with her employer (bi-co).
TT seems to suggest she has a writing business, etc. but she obviously doesn't, this was simply a one time job/grant. How should we proceed?
