Browse credit cards from a variety of issuers to see if there's a better card for you.
It should be in the header of the page that lists your transactions. If you click on the rewards amount, you should get to another page where you can redeem rewards or view more details. The "View Rewards Transactions" link on the bottom of that page would list the rewards earned for each transaction.
Your current card is likely good to go as a QS right now. I don't think activating the replacement card will make a difference. I'd bet on the rewards info appearing once you make a charge that earns a reward. After that, when you redeem and have a balance of zero, the zero amount will show up.
