Hi there, @gksteele6205. Thank you for returning to the thread and following the suggestions provided by my colleague. I'm glad to step in and assist you with voiding your checks.

If you already see the Delete, Edit, Cancel, or Save options, simply click Edit to reopen the check transaction. From its window, click More and select Void. Then, choose Void Transaction to complete the process. 

Please see the image below for your reference.

Concerning the date of the reversing entries, you're right to question this. The reversing entries should indeed be recorded on the date of the original check (in your case, 7/10/2023). This maintains the accuracy of your financial records for the period when the check was initially issued.

If the transaction was already reconciled, then I suggest following the recommendation shared by Rainflurry.

For further guidance on handling stale checks in QBO, I recommend reviewing this article: What are Stale-dated Checks? And What To Do With One?

Additionally, I recommend consulting your accountant for professional advice on managing stale checks. Their expertise can ensure your books remain accurate and compliant with relevant regulations.

If you have any more questions about this process or encounter any issues, please don't hesitate to reply to this thread. We're here to ensure you can manage your finances accurately and efficiently.
