Yes, definitely you can find your private key, assuming that the wallet that you have is a non-custodial wallet, i.e. like Electrum that you have total control of if. But if you have a wallet like in a exchange, then you will not find your private key since it is a custodial wallet and the exchange owns the private key.

So we really have to know what kind of wallet you have and then maybe we can advise you on how to get the private key. Just be careful, maybe someone here will message you that they will help you out about you private key as they might have the intention to steal your Bitcoin from you.
