Hi WKKU,
Thank you for reaching out Microsoft Community. We're sorry to know that you still haven't received the return label.
If you place this repair order online, the return label should be sent to the email address associated to your Microsoft account. If you can't find it in your inbox or in the spam, it's best to contact support so that they can re-generate a return label for you and that label contains the information as to where you can send the Surface device.
If this answers your question, feel free to mark this post as an answer. Otherwise, don't hesitate to contact support for further assistance.
Kind Regards,
Crest_Z
