Deductions & credits

Everything I’m reading says domestic workers such as personal care aides/health aides are not self employed or contractors and they are employees. I have read conflicting statements about claiming mileage in 2021 however. I don’t know if I can claim the mileage. I did get a 1099-NEC from the platform I use for some of the people but the same platform states that I am not a contractor but an employee. Thank you for your help.
