Ok so I found the transaction as a "P2SH-P2PK" change address. But I guess I need to find what private key that is and add the prefix "P2SH-P2PK:privatkey", but how will I know which private key it is? Do you know that HCP?

In other case I can create a new wallet and import the private key one by one and see which one that hasn't any transaction and add the prefix to it?

Edit: Tried to take one private key that didn't have any transaction when importing it and add the prefix "P2SH-P2PK:" but the "next" button wasn't enabled...

It's p2wpkh-p2sh: as written in the 'info'.
View HCP's post's 2nd image, the "Wallet Properties", from there expand where the address belongs and double-click the address;
Click "View Address Keys" to get its private key.
