For Car A - Work through the business vehicle section and select the option for "I stopped using this asset/vehicle in 2020" and continue working it through. When presented the "Specialy Handling Required?" screen, read that screen so you'll understand why I'm telling you to click the YES button. Then click the YES button. Finish working it through, and that does it. You will "NOT" be asked for a sales price of the vehicle, but you WILL be asked for a "date of disposition" that you will need to enter. Typically, this would be the last day the vehicle was used in the business.
