I was confused for a moment and added money to my apple store
Now I can't request a refund for the money back into my bank account.
Do you mean you have added funds to your Apple ID balance?
If so, See -> Check your Apple ID balance
Check your Apple ID balance – Apple Support (UK)
scroll to ⤵️
If you have Apple ID balance you can't use.
You can't redeem or return Apple Gift Cards, App Store & iTunes Gift Cards or unused Apple ID balance for cash, except as required by law. If your jurisdiction allows the refund of redeemed gift balances, you can contact Apple Support to request a refund.
When you contact Apple, include the following information:
• Your Apple ID.
• The refund amount.
• Your current delivery address.
But you can use that funds to buy apps.
See -> Change, add or remove Apple ID payment methods

- set your Apple ID balance as your default payment.
If you update your payment method or add funds to your Apple ID balance, It would take about 1 to 3 business days in order to process.
If you're still unable to update your payment method, Contact Apple Support.
