Try to switch a network in your wallet. What wallet is it?

I did this big mistake twice ,with 2 transactions , and what I have to do, my wallet is ledger nano x , but the support team are not reachable now, please help me

We can’t help you. Can give you an advise and direction
Go to, connect your Ledger, switch the network to Ethereum and make a transaction
