Yes, you can delete the credit card account, Deej4.

I'll guide you how:

1. Click Lists. 
2. Go to Chart of Accounts.
3. Select the account, right-click, then select Delete Account.
4. Click OK to confirm. 

Although, I'd suggest reaching out with your accountant before deleting it since this might be affecting your reconciled balances or closed books. 

If in any case, you're unable to delete it, you can make it inactive instead. This account will not show in the Chart of Accounts and you can make it active again. Here's how:

1. In the Chart of Account window, select the account.
2. Right-click, then select Make Account Inactive.
