Hi, @PBTaS. I'm happy to help you out with this! Do you have any other payment methods, like PayPal or Klarna for example, connected to your shop at the moment?
If these two payments were captured through Shopify Payments they will be added to your Shopify Payments payout schedule. You can view your scheduled payouts by following the steps in this guide. From your Shopify admin you'll want to go to Settings > Payments > View payouts (in the Shopify Payments section). From here, you can find the details of a specific payout in the payout schedule by clicking the amount of the payout, or in the All payouts section by clicking the date of the payout.
