Get Refund Status for Trackings

Hello, I recently started using WooCommerce Shipping and have created several shipping labels. However, I have refunded or requested a refund for some labels (all of which are unused and will not be used). How can I check the status of these refunds, and when can I expect them to be processed? I was charged at the time of label creation, so I’d like to know when the refunded amount will be returned. Thank you!
