There is nothing on the return that would necessitate that form. This has been double- and triple-checked. The only place where sale of business property is mentioned at all in the return is as part of the home office deduction section (needed for my state return even though it no longer works as a federal deduction), and the answer there has always been that no business property was sold. The system seems to be including the form as a default and then linking the required upgrade to the presence of the form -- which has never been needed, contains no data, and is undeletable.
