Sponsored products ads attributions and returns

New to sponsored ads. I am trying to understand if returns will be part of the sales attributed.

The rules sale attributions does not include canceled, returned, or declined – and then state 72hours of order creation.

So is returned within 72hours for my fba orders or just auto declined for 72hours?

Or it’s returned within 30 days and then everything will be recalculated and I need to go back and see final numbers once again?
