Returning back to Apple warehouse directly using own shipping label

I don't live near an Apple Store but while traveling I bought something from an Apple Store while traveling that I want to return still within the 14 day window. The customer service told me there's a way to request to return the item by mail, but Apple isn't sending me a return shipping label. What address do I send it back to?

45 Logistics Drive, Carlisle, PA 17013.

What happens if I just put my purchase receipt, a note to return or the return authorization note, and ship to that address or an Apple store directly?
