Do you use the simpleos wallet? You can see your tokens there or on eostoolkit (just chose search account and put in your account name or public address) or you can use eosflare to view all transactions in and out of your account.

Like aclarkuk82 said, you don't need to do anything to claim your IQ tokens. If you had them before genesis snapshot (which means you bought and had EOS as an ERC20 token and registered it) they will be airdropped automatically.
