I'll provide information and steps to show the wages in the reconciliation window.
Since you're unable to find journal entries for October wages, I'd suggest visiting the Audit log page. From there, you'll see a list of the company's activities, the changes made, and who made them. That said, it could be that one of the QuickBooks users made the changes or deleted the journal entries for wages.
Click the Gear⚙ icon and choose Audit Log.
Select the Filter drop-down button.
Use the fields on the Filter panel to choose the appropriate User, Date, or Events filter to narrow the results.
Once verified that the journal entries for October wages are still there and no one made changes to it, I'd recommend checking the status of the transaction. This is to identify if your JE has been cleared or reconciled in the register. It might be the reason that the wages were not in the reconciliation window when reconciling October.
Go to the Accounting menu. Then select Chart of Accounts.
Locate the account and select View register.
Find the transaction.
Review the check column. If the transaction is reconciled, you’ll see an “R.”
