Donated Vehicle but turbotax ask me date of purchase of vehicle, basis cost and FMV of vehicle

Donated Vehicle but turbotax ask me date of purchase of vehicle, basis cost and FMV of vehicle. But I don't have this information anymore. Isn't the info of my donation already listed on the 1098 form, why is the other info needed? And if I don't have the other info does that mean I am not able to take the deduction with the state (California)?
