I need help, anyone wanna solve my issue

Hi everyone ,
I need help with searching for a return address because I was using shapeshift and I had an issue there but they need a return address from my counterwallet , anyone know how to find the return address. I need a list of steps to find the return address, please help anyone.

Whatever address it displays when you log into your counterwallet is the return address.

you mean the public key for my counterwallet ?
Shapeshift tried that and said its not valid
