Deductions & credits

Thank for the guidance.  IRS states, “You must file one or more Forms 8283 if the amount of your deduction for each noncash contribution is more than $500. You must also file Form 8283 if you have a group of similar items for which a total deduction of over $500 is claimed.”  


Example: I make five donation runs in one year for clothes and household items.  Each donation run is $500 or less of clothes/house goods.  On 8283 form part 1 section A notes, it states “If the amount you claimed as a deduction for an item is $500 or less, you do not have to complete columns e, f and g.”  I’m probably overthinking this, but it’s not crystal clear to me.  Is the $500 the total amount for the year, or is is it per donation event?  That whole “…for each non cash contribution” statement is confusing me.  Am I required to fill in sections e, f, and g based on that scenario, and do I provide info for e, f, and g for each line item deduction?  Thanks in advance.
