First navigate to your Online Store dashboard and click Orders. Click on the order in question to open the Order Details page. You should then see a refund option in the top right corner. You can check/uncheck the items you need to refund before submitting.
The shipping label will automatically refund as credit to your Shippo account if the label is not scanned within 2 weeks. If you setup a UPS account through Square then the label will not be billed to you if it is not scanned and shipped through their system.
