How do I document the donation of a vehicle I received as a gift? TurboTax says it appreciated in value since it was sold for $700, which is false.

In 2012 I received a used car as a gift; I donated to a charity in 2019 that sold it for $700. When I enter the purchase price as $0 and state it was a gift to me, Turbo Tax says the car appreciated in value. That's not true.
