We live in Delaware. There is 4.25% on purchase price of a car. Is this the personal property tax portion of the registration fee?

We live in Delaware, and we bought a car in 2018. When we go to DMV, other than the $80 registration fee, we also paid a documentation fee of $1147, which is 4.25% of the purchase price for the car. Is this $1147 considered to be the personal property Tax portion of the registration fee even if it is labeled as documentation fee? I am asking this because when I am doing the expenses for my rental property, for this new car, it asks for the personal property Tax portion of the registration fee
