In-app tracking shows my item "arrived at post office, available for pick-up" ...in another country

Recently bought something from a U.S. seller. They shipped via "Global Postal Shipping" and there is no tracking number provided for me to look it up with a courier, can only track it in the Etsy app.

Seemed to being going well until at some random town in the U.S. it's suddenly listed as "arrived at post office, available for pickup" Google seems to say this means I should go to that particular post office to pick it up. Really hoping that is not the case?? Was really hoping to have this thing delivered by Christmas :(

I'm worried the seller somehow got my address wrong?? I've used the same address with many purchases made overseas and never had issues.
