Returning damaged AirPods

I received my replacement AirPods and I am confused on how to send them back. To me, the instructions weren't that clear. I never received a return shipping label. The return instructions say to peel off the top label and keep as a receipt, which label is that? The labels on my box are stuck on pretty good and if I were to peel it off, it wouldn't come off in one piece.

Anyone know how to do this exactly? Ive reached out to Apple Support and they just kept sending me a link to the instructions.
