I appreciate you joining in this thread, Gravity.

I'm here to help you with reconciling your account and ensure the balances are equal.

In QuickBooks Desktop, eliminating or adding a reconciled transaction will affect your beginning balance for the next reconciliation.

To isolate the issue, you might want to check if there were changes made to your transactions. You can pull up and run the Audit Trail report to see if there are any modifications.

If there were transactions that have been changed, voided, or delete it will not balance your accounts. It would be best to have the old copy of the reconciliation while redoing it so you can determine what's missing and what's been changed. Doing so will help you ensure the accuracy of your financial records.

However, if there no changes, verifying and rebuilding your data is a good start when it comes to fixing data-related issues in QuickBooks Desktop.

To Verify Data:

1. Click Window at the top menu bar, then Close All.
2. From the File menu, choose Utilities.
3. Tap Verify Data.
   

To Rebuild Data:

1. Click Window at the top menu bar, then Close All.
2. From the File menu, choose Utilities.
3. Hit Rebuild Data.
   
4. You will receive a warning message to backup your company file, press OK.
5. Click OK when you get the message "Rebuild has completed".
