UPS payment at delivery question

Apparently, one of my shipments was charged with 10% tariff and UPS wants me to pay the amount. The lady spoke from UPS said they’ll make delivery attempt once the payment is made.

However, the thing is they have already delivered the package to the Amazon warehouse today.

Has anyone experienced this?

What am I supposed to do here? Make the payment to UPS? Or is this done with?

Edit: the package already cleared customs and stuff so I’m not sure who that money will go to. Did UPS pay on my behalf? Do I owe the money to thr govt?
