You need to change that tracking where you marked the item as dispatched.
Using a laptop / PC and Chrome you should be able to do this manually, if not contact eBay Customer Services they can do this for you. When that tracking has shown delivery, when 2 days lapse after that delivery date, your payout will be released.
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.
