Step 1: You can go to [Refund After-Sales Management] - Select [Return (shipped)]:

Step 2: After the buyer initiates a refund, the seller has 5 days to choose to agree or reject the buyer's return application based on the status of the transaction; if you refuse to return the buyer, just click "Reject Refund Application"; if you agree, click "Confirm Refund Application"; if the seller does not respond after the deadline, the system assumes that the seller agrees to the refund and gives the return address. If the seller agrees to return the buyer, after clicking "Agree to Refund Application", you need to confirm whether the return address is correct. If you need to modify it, click "Manage My Delivery Address" to set it. At the same time, you need to leave a message to the buyer to remind the buyer of the matters needing attention for return.
