Gerald, you should have received some of the mailbox info (keys, box number) via your closing. The location would be whatever mailstop is associated with your Village.
You can send a change of address (temp or permanent) to the post office at whatever zip code is associated with your TV address so future mail can be forwarded to wherever you'd like. I'll assume you're going to have someone looking in on your TV home when you're not there. Send them a mailbox key and have them bundle up what's already in the box.
If it's a resale, make sure the previous owners filled out a change of address to have their mail forwarded. Even with that, sometimes the post office can make a mistake and overlook an address change. That's what happened with us on our resale purchase. I simply reached inside our TV mailbox and taped a polite note across the inside opening of the box noting forwarding info for both the previous owners and us (we're not in TV often enough to want to get our mail there).
Hope that helps!
Bill
