When you get outbid, the original bid amount will go back into your wallet. You can see this by going to Etherscan using this link and looking up your wallet address. Enter your public key (also known as “wallet address”) in the search bar. Here, you’ll be able to see all of the transactions that have been executed with your wallet, both incoming and outgoing. To see the returned bid click on the "internal txns" tab.
