Deductions & credits

Thank you, Alicia. My concern is that Turbotax is asking for the sales price (business portion only) of the old car, what its value was when I started using it for business, etc. (because I have checked "I stopped using this car in 2021."),  I'm confused about how to answer these questions as safely as possible, since I'm not sure of many of the numbers. I traded my car in rather than selling it, and the percentage of use for business was 10% at the very most.
