Commercial Property Sale with Asset Depreciation

I sold my commercial property in July 2021.  (self rented for my own business, which was also closed.)

I have separated the building and land in the sale (under Rental Properties) when I indicate the building has been sold.  Is there a step-by-step instruction to handle the building improvements that were added as separate items each with their own depreciation?  I have told Turbo Tax the assets have been sold with the building sale date.

Thank you,
