The steps given above are for QuickBooks Online, Ann35.

You can do a mini reconciliation instead. Mini-reconciliation is a method that uses an "off-cycle" reconciliation which means that you leave the reconciled periods to correct the current balance. Here are the steps on how to do a mini-reconciliation:

1. Go to the Banking menu then choose Reconcile.
2. Select the bank account with the transactions you need to reconcile.
3. In the Statement Date field, enter date for an "off-cycle reconciliation." This date can be any date between your last reconciliation and the next scheduled one.
4. Enter the balance of your last successful reconciliation in the Ending Balance field then click Continue.
5. In the Reconcile window, check off the transactions you are fixing and re-reconciling.
6. Make sure the Difference field shows $0.00.
7. When everything looks good, hit Reconcile Now.
