Hello, @PJSASSONE.
When you close your books and add transactions from the previous period, it will cause imbalances in your financial record.
To resolve this issue, I recommend reopening the closed books and reversing the reconciliation. Afterward, it is advisable to re-do the reconciliation for the relevant period and then finalize it. If the transaction is related to 2024, it is important to date the checks under that particular period.
If the situation becomes significantly complicated, I also advise seeking assistance from an accountant to help you resolve outstanding checks from previous years.
I'll include this article for tailoring financial data to specific business needs, allowing for better decision-making and comprehensive analysis: Customize reports in QuickBooks Desktop.
