I've got you covered, briancliffordcol.
It's my priority that you're able to enter this check, so I'd be happy to lend you a hand in taking care of this.
To clarify, where did you check your reconciled balance? Do you go to the Reconciliation page to check your current beginning balance (ending balance of the previous reconciliation) or just in the bank register?
If you checked the Reconciliation page, then the most likely reason why you can't see it in the register is that it may be using the wrong date. That being said, a quick way to find it is to use the Search Tool. Here's how:
However, if it's the latter, you could still follow these steps to locate the check and make the corrections. But, you'll need to manually reconcile it to make sure that the Beginning Balance of your next reconciliation would be correct.
All of this information and more is available in our guide on how to Manually clear, unclear, reconcile, or unreconcile transactions. Lastly, please be sure to consult your accountant before following these steps. this is to ensure that there will be no discrepancies to your books.
That should do it. Please stay in touch if there's anything else I can do for you. Thanks for reaching out, wishing you and your business all the best!
