Deductions & credits

This doesn't completely answer my question.  When Turbo Tax asks me if I have a 1098-C or a written statement certifying the donation of the car, I fill out the information indicating that the charity is using the vehicle by checking box 5a and also 5c and indicating that the vehicle is being used by the charity.  It then states "Your Entered Value is Different" because there is no sales price to put in box 4b because the charity did not sell the vehicle.  Under the choices for this section, it includes "the charity made significant use of the vehicle before they sold it", "the charity made a material improvemetn to the vehicle before they sold it" "the charity gave or sold the vehicle at a reduced price to a needy individual" and "none of the above".  Because the charity is keeping and using the vehicle and has not sold the vehicle, if I select "none of the above" I then get no credit for the donation.  This does not seem correct.
