@Woodcarver It's been a while and I don't recall a need to identify storage location when setting up the POS. Your account may be deactivated. I'd suggest calling reactivation support at 855-700-6000. I assume you are the authorized representative for the account (if not they won't be able to help you).
This thread might have some back and forth that you'll find helpful.

Take care of yourself and, as life provides, someone else too.
