You can check your stETH balance on Etherscan by clicking the token in the dropdown menu. Rebases happen once per day at 12PM UTC. There is no transaction that takes place, as a way to prevent paying gas fees on a daily basis. We are launching a rewards page shortly which will let you see your daily rewards.
Your staking rewards are applied to your stETH balance.
