Travel Nurse with W-2, separate tax home, mileage, and employer provided reimbursement for hotel/AirBnB

Worked as travel nurse 2018, tax home 4 hours away from assignment. Got W-2 from "employer", they also gave me per diem for hotel/AirBnB while on assignment.

Should this be a Schedule C, or a direct employee with mileage and hote/AirBnB expenses?
