Hello there, GNJRox.
After creating a journal entry, we'll also need to reconcile it. We have the option to manually reconcile it or undo the reconciliation to include the JE we created. This way, it'll affect both the ending and beginning balance for the next period of reconciling the account.
I have a reference here that you can check out for more details on how QuickBooks handles reconciliation.
Feel free to get back to me if you need anything else. Thanks!
