The easiest way to find a Tezos transaction hash is to use the Temple wallet. To do this, simply log in to your Temple wallet and navigate to the Activity tab. Here, you will see a list of all the transactions you have made with your Tezos wallet. Each transaction will have a unique transaction hash associated with it, which you can use to track the status of your transaction. Additionally, you can use tools such as Tezblock, Tezos.id, and TzStats to search for your transaction hash and view the details of the transaction.
