I'd like to share what I know, IMCB.
I can see the importance of having the option to undo reconciliation in QuickBooks Online. This can save you much time to do other tasks.
At the moment, the option to undo the entire reconciliation is only available in the QuickBooks Online Accountant version. You can invite your accountant to access your account and let them do it on their end.
If you want to manually undo your reconciliation, you can follow the steps provided by my colleague AlexV above. For your reference, please check this guide: Undo or remove transactions from reconciliations in QuickBooks Online.
On the other hand, you can make yourself an accountant. This way you'll be having the option to undo it on your own. No worries, it's free of charge as long as it only includes one client. I'll show you how.
- Click the Gear icon.
- Select Manage Users.
- Go to the Accounting firms tab.
- Enter the email address, then hit Invite.
- Check your email coming from Intuit prompting you to set up your firm. You can take the default one.
- The next time you'll log in to your QBO account if your using the same email address will be on the QBO Accountant version.
Adding this resource here if there's a need for you to make modifications: Enter an adjusting entry for a reconciliation.
