How do I un-reconcile a bank statement for QB's online? I do not have an accountant setup, I do my own reconciling and I need to undo last months but can't find a way.

How's your day going, @dlebard-donumdei?

I’ll be your guide today, so you can unreconcile your bank statements in QuickBooks Online (QBO).

We can manually undo each transaction in the bank register. I'll guide you how:

1. Go to the Accounting menu, and then choose.
2. Select the bank you’re working on, then click View register.
3. Click the Funnel icon to filter the dates, then choose Apply.
4. Locate and click the transaction, one at a time.
5. Between the Deposit and Balance (USD) columns, keep clicking the R field until the status changes to a blank (unreconciled) or C (cleared).
6. Click Save.

Please follow the same steps to reconcile multiple transactions. For future reference, check out this article for more details: Clear, unclear, reconcile, or unreconciled transactions.

Once done, you can start reconciling the account. I’m adding a link that covers everything you need to know about the reconciliation process: Reconcile an account in QuickBooks Online.
