To properly track credit cards in QuickBooks, set up a credit card account. Enter the individual transactions in the account register much like you do a bank account (or use the credit card charge transaction form, which works like a check in the bank account.)
Then when you pay an amount, record a check from your bank account using the CC account. It effectively becomes a transfer to the CC account, reducing it's balance. This is much like a check written against a loan, which also pays down its balance.
