How can I fix schedule C vehicle expenses? I have 2 vehicles and TurboTax is asking for a date when the first vehicle was sold, it is still in use.

On schedule C vehicle expenses, I'm getting an error and TurboTax wants me to fill in when this vehicle was sold. It says "date sold must be entered" however, I'm still using it. It was not used for a couple of months while waiting for the engine to be repaired so I was able to use my other truck. How can I avoid this error from TurboTax?
