I'd like to share some insights about handling reconciliation in QuickBooks Online, @meganohearn.

Editing earlier reconciliations require extra care. Undoing a reconciliation also undoes all following reconciliations follow. When you undo a reconciliation, you'll have to make sure that you're logged in to your account using the QuickBooks Online Accountant. Then, you'll have to locate and open your customer's QBO company.

Once logged in:

1. Open the Accounting menu.

2. Click on the Reconcile tab.

3. Choose History by account.

4. Choose the account you want to reconcile and the date range from the dropdowns.

5. Locate the reconciliation on the list.

6. Choose View report to navigate to the Reconciliation Report.

7. Review any discrepancies and changes your client wants to make.

8. Once ready, select the dropdown ▼ in the Action column, and then hit Undo.

9. Click on Yes and then hit Undo to confirm.

For more information about the process, check this out: Undo a client’s reconciliation in QuickBooks Online Accountant.

Here's also a guide on how to resolve errors on previous reconciliation: Fix issues for accounts you've reconciled in the past in QuickBooks Online.

Loop me in for additional banking concerns. It's my pleasure to be of help. Take the best care!
