i did that, BUT it's wrong because my output paths don't match, neither does the private key to the address. I have to create a wallet with a withdrawal path suitable for a private wallet, because initially electrum creates it differently, I need m/0/58
A private key which starts with "K" is already at a derivation path. It was reached by deriving to the specified path and then calculating the wallet import format key at that path. You cannot use that key in isolation to derive further child keys.
If you have either a seed phrase, or a master private key or extended private key beginning with xprv then you can start deriving child keys and derive the key at m/0/58.
