Hello @David-And-Dawn1,
You don't have to do anything.
when you add something like a bakn account as your payout method Airbnb makes a 1 cent deposit to it. If that is accepted by the bank Airbnb automatically continues the verification process. when this is complete the status of your method is set to "ready" so you payouts will then be sent to that account.
You can check the status as follows:
click on your profile photo after logging in
then select "Account settings" from the menu
then click on "Payout preferences"
check the "Status" column for the payout method you entered.
In my case it took several working days to complete this process.
Steve.
