Hello @Julie583,
If you have email notifications enabled Airbnb should have sent an email on Saturday, 24 hours or so after the guest checked in, saying that they have released your payment.
That was on a weekend and if your payout method is to your bank account the money may not appear in your account until later today or maybe tomorrow, Tuesday.
You should aslo see it in your transaction history. Click on your profile photo, then on "Account settings" and then on "Transaction history".
When do I get paid?
Steve.
