I have a vehicle that was used for business but is now a personal car. i always used the standard mileage deduction. Do i enter $0.00 on recapture form?

I have never filed a section 179 depreciation, but turbotax is saying I have to file for a recapture. Since I have to enter something, do I just leave it blank at $0.00 for the amount? I don't want to raise any red flags but want to make sure I have entered and given all information needed.
