Open QuickBooks, click "Lists" in the Menu and select "Chart of Accounts." A list of all of your accounts appears.
Double-click your credit card account to view all of the transactions completed with that account.
Click the first transaction in the list and then click "Edit Transaction." Information about the transaction appears in a new window.
Click "Delete" in the toolbar. A warning appears informing you that the transaction was used to pay a bill, and that deleting the transaction makes the bill outstanding in QuickBooks. Click "OK" and then "Save & Close" to finish deleting the transaction.
Delete the remaining transactions associated with the credit card account. Intuit does not include a mass-delete option for transactions.
Right-click the name of the credit card account in the "Chart of Accounts" window and select "Delete Account." Confirm the deleting action by clicking "OK."
