You will benefit from reading the articles in the Help Center about payouts and deposits. As a new host, there are sooooo many details about the platform that are not intuitive, so a good place to become educated is the Help Center.
In your case, as a new host, Air BNB will often hold the payouts for 30 days. After that, you should expect the payout to be sent 24 hours after check in. As to security deposits, those are never collected by Air BNB unless there is a valid damage claim.
Good luck and welcome to hosting!!
