How to report donation of inherited items

We entered all of the items that we inherited and then donated into It's Deductible. Turbo Tax is now asking for the purchase price, date acquired now acquired and method used to determine value.


I'm unclear if I should enter the estimated amount that was paid originally for the items or enter zero because they were inherited by us. Also should the date acquired be the date of the relative's death or "various" since the items were all purchased over time?
