How can I change the tracking number after I’ve already purchased and printed the label through eBay. When I went to ship it USPS said I needed additional eight dollars of postage added to what I had already purchased through eBay. That additional postage added a new tracking number, I can’t seem to update that here

In your sold items list click add or edit tracking.  You should be able to add it a second tracking #.
