Should my business vehicle be listed under both Assets and Vehicle Expenses? I took full 179 deduction on it last year as Asset, so it seems I shouldn't deduct any more?

Turbotax has my vehicle listed and fully depreciated as an Asset for 2017, when I purchased the vehicle.  But it also has the vehicle listed under the Vehicles section, and seems to want me to input actual expenses. Since I already fully depreciated the vehicle last year through Section 179, it seems as though I should not go after any further deductions pertaining to it.  However, I'd still like to deduct gas expenses, and not sure how to do that if I remove the vehicle from the Vehicles section, and keep it under the Assets section only.
