Let me provide some details to guide you on what to do with the other card, PalmParrot.
Generally, the most common way to set up a bank account or credit card account with multiple cards associated with it is to create a parent account and then have each individual card set up underneath as a subaccount.
Before you connect to Online Banking, you'll have to know how the bank sends the downloaded transactions. If the transactions download to one account, you can connect only the parent account. If the transactions download to the individual accounts, connect the subaccount and not the parent account.
After you knew how the bank sends the downloaded transaction, you can check out this article for more detailed steps on how to create a subaccount: Create Subaccounts In Your Chart Of Accounts In QuickBooks Online.
Furthermore, learn how QuickBooks add or try to look for a match with transactions you've already entered in your QuickBooks account. I've got this article for additional information: Categorize And Match Online Bank Transactions In QuickBooks Online.
