Try going to your Purchase history.
Find the item in Returns and cancelled orders.
Select View return details.
Choose See label.
If the label is printing blank:
When the return label print window opens, do not use the PRINT button at the bottom of the page. Instead click on the ">>" at the upper right of the window and either use the Print or Save option there.
If none of the above helps, you will have to call ebay to email you a copy of the label.
Best to also get an acceptance scan from the carrier, especially if close to the cutoff date. Otherwise, one day late getting scanned and seller can have ebay close case in his favor.
