For Step 2, yes — you're correct. Since you want to increase the credit card G/L account without affecting the bank reconciliation, you can create a G/L journal entry like this:
Debit the appropriate expense account (e.g., Travel, Office Supplies — whatever the $300 was for).
Credit the Credit Card G/L account to show that it was used for payment.
This way, the amount is properly recorded as an expense, and it increases the credit card balance — without showing up in the bank ledger again.
Hope that clears it up!
