Hello @valius55,
Welcome! Thanks for joining the PayPal Community Forum. I'm sorry to hear you've run into some issues refunding a transaction. Has the transaction completed to your PayPal account yet? If not, you normally won't see a refund button until the transaction completes to your PayPal account.
If it has, you may want to try reaching out to our Customer Support teams for assistance.
Good luck and best wishes!
- Jon K
