You cannot change that tracking yourself but will need to contact eBay Customer Services to do this for you. The lines are currently closed but will reopen in just under 2 hours at 8 a.m.
If for whatever reason they cannot your payout will be held for 14 days.
This is the easiest and quickest way to contact eBay Customer Services, for a Call Back option.

Lines open between 8 a.m. to 10 p.m. on weekdays.
9 a.m. to 6 p.m. on weekends.
I recommend contacting CS very first thing in the morning, when the lines first open, as there's more chance of Dublin answering.
