My reconciliation reports are a month ahead.

Thanks for reaching out to the Community, @ckfoodbank.

QuickBooks Desktop (QBDT) remembers the last calendar date entered on a reconciliation. So if a future date was entered, the Reconcile window and the reconciliation reports will default to that future date until it has passed.

To fix this, you will need to undo the last reconciliation to reset the last reconciled date and remove the Previous Reconciliation report for the corresponding date.

Here's how to do it:

1. In QBDT, go to the Banking menu at the top and pick Reconcile in the drop-down. 
2. In the Begin Reconciliation window, select the appropriate account, then click Undo Last Reconciliation.
3. A message to backup the company file before undoing a previous reconciliation is displayed. If you have already created a backup, tick Continue.
4. Click Ok when the message Undo Previous Reconciliation has completed displays.
5. Reconcile the transactions again. Make sure the correct dates are entered.

The problem is these reconciliations are dating back to Jul 2020.  I don't think I can reconcile that far back with out screwing up everything.  My question applied to the next reconciliation.  Can I just make it November 30th, even though November 30th was used?
