Hi @Kathy104,
Welcome to the Community Center! I have moved this question here to a new thread - it's best to put new questions in separate threads, as otherwise they get lost in other discussions and are harder to find! I have removed your other posts asking this same question so that any advice you receive is all in the same place. I have given this post a title, please let me know if you want to change it!
In terms of your question, I suggest you read this Community Help Guide which explains how the payment process works. This Help Guide about payouts will also be helpful. Guests pay when they book but Airbnb holds the money until 24hrs after the guest checks in, when it is then released.
I saw on one of your other posts that you hadn't yet input your payout details? This Help Guide explains how you add a payout method.
I hope that helps, let us know how you get on!
Kirstie
