Why is Turbo requiring a Date Acquired & Donor cost if total deduction is over $500 but no single item is over $500. IRS instructions & form state this is only required if AN ITEM is claimed for over $500.

Actually, the IRS says this:

If you claim a deduction of more than $500, but not more than $5,000 per item (or a group of similar items), you must fill out Form 8283, Section A.
