Sold a Schedule C vehicle

My husband has done a self-proprietor business since 1987 and we've had a vehicle for that use with records of mileage but sadly we used the depreciation methods.  Our last vehicle was put into use in 2011 at $19721.  Throughout the years of business and personal use $13017 was depreciated.  Leaving an adjusted basis of $6704.  We haven't used in the vehicle for more than 50% business use in several years, just a few 100 miles as business slowed.  In September 2024 we sold the truck for $4500.     At this point I do not recall which depreciation method we used in 2011 and beyond, I just let Turbo Tax figure it out and it hasn't been giving us depreciation for a few years (less than 50% use for those year.)  We never carried an inventory since it was a carpentry business and what he bought he made cabinets and installed them.  But he was occasionally making some income so I kept the Schedule C going.   I am considering it as a closed business, we did not sell it. But how do I deal with the truck sale?  I said this year that we converted it to 100%personal use. And then we sold it for a good price because it had less than 80,000 miles on it.  I am trying to figure out how to the Form 4797 page 2 enterable form for this.  There doesn't seem to be anywhere to enter the sale price, for example.
