How do I remove credit cards from the drop-down in Expense Entries?

The credit cards listed in the Credit Card drop-down on the Expense Entries screen come from the Chart of Accounts screen. To remove a credit card from this list, you can either delete the credit card account or make it inactive from Accounting > Chart of Accounts.

However, accounts that are linked to existing transactions or settings cannot be deleted or made inactive. Check CORE Help Center for details.
