Ted here from Shopify, thanks for reaching out to us!
If you view the order in your admin, and scroll down to the history of the order, you should be able to see the exact payout date that the payment has been added to. Here is an example of how that would look. Can you view this in your admin and let me know the payout date?
As well, depending on your location, your pay period with Shopify Payments can take between 2-4 business days to complete. Your pay period refers to the amount of time between the day the customer places an order at the checkout and the day the funds from that order are sent to your bank account. As mentioned above, pay periods depend on you location but more info can be found in this guide if you would like to take a look.
Please let me know how those goes!
