How do I delete an entry in Sale of Business Property?

This could have to do with an item from your business such as a car that you stopped using. You can delete the item by going back into the interview and deleting it. Here is how:

• Business 
• Less Common Business Situations
• Sale of Business Property...update...continue...you should see a summary page (see screenshot)...delete the item
• The amount should not be next to Sale of Business Property any longer
• If you did not have an item to delete or if the amount is still there, the sale is probably from an asset in your business that you sold or stopped using...go to the vehicle or asset section of your business

To clarify, are you trying to delete 4797 from your Turbo Tax return? Can you be more specific with your issue?
