Creating shipment plan

Hello. I am creating my shipment plan and I picked UPS Non Partner. I got a warning saying I am suppose to attach the alternate address to the box but the alternate address doesn’t come with all the bar codes Amazon generated when creating the original shipping label. So am I suppose to print the the label that Amazon generated and also print out the alternate address and apply it to the box. Or just tell UPS directly that these are the same address but Amazon asked me to use this address?
