@Mark-and-Kerrie0:
Go into your admin panel and click on your tiny picture in the upper right corner.
Click Account settings.
Click Payout Preferences.
You should now be able to see your payout method and banking information.
Third column over is the Status column. This should read "ready" next to your information.
Once you input your banking information Airbnb should have made a tiny deposit to your account. This make take a few days. In my case it was 1 penny. If you received and confirmed that deposit and the status is "ready" then you should be set to go.
