If you are on the managed payments then ebay take the payment and once they have taken their fees pay the remainder into your bank account.
On the seller hub you can see the progress of payments
If ebay have told you that you have been paid and to post then you have to post
You dont wait for the payment to be in your bank as that can take several days
