Deductions & credits

If you are not claiming 100% business use for the vehicle (and I doubt you are) then you are taking the "per-mile" deduction. For 2019 the per-mile deduction is 58 cents per mile. That will include vehicle depreciation, insurance, registration, the whole works. So you can't deduct other "itemized" vehicle expenses.  Besides, depending on the actual business miles driven as a percentage of personal miles, you'll more than likely find the per-mile deduction is actually higher.

Do note that you can only claim vehicle use if you are self-employed. If you are a W-2 employee then absolutely nothing in the way of work related expenses (including vehicle use) is deductible.
