You do not have to use eBay labels, I never have, just add any tracking to where you marked the item as dispatched.
If you can do so now, add those numbers manually , Once tracking shows delivery payout is released 2 days after that delivery date. You may need a PC / laptop with Chrome to do this.
If you cannot change or add tracking, you will need to wait 14 days for that payout to be released into your eBay Balance.
