The information I have given should solve any problem. As you go through the program, indicate that you sold the property on the first screen showing in my answer. As you progress, enter that you sold it on the date in 2018, say that you used it 100% for business and that you had zero personal days. It will generate the sales information based on the amount you put when you first converted the property to business use vs the sales price. You will have to recapture depreciation.
