Is this the first payment you've received through your Stripe account?
This is what Stripe's support says on this issue: "The first payout for every new Stripe account is typically paid out 7 days after the first successful payment is received. This waiting period can be up to 14 days for businesses in certain industries. This delay allows Stripe to mitigate some of the risks inherent in providing credit services.
You can confirm your payout schedule and estimated payout timing in your Dashboard.
This initial payout timing requirement cannot be waived. Any changes made to your payout timing or payout method during this time will take effect after this initial delay.
More information on payout schedules can be found here."
Did you check the box 'Process' when entering the payment?
