Good day, thirdinrev.
Allow me to help you delete reconciliations for the past few months due to discrepancies occurring due to changes in QuickBooks Online.
If you already reconciled the account, you'll need to undo all the transactions that were reconciled and manually check each transaction for changes made.
Here's how:
- Go to Accounting from the left menu and select Chart of Accounts.
- Locate the appropriate account.
- Choose Account history from the Action column.
- Select the transaction.
- Go to the Check (/) column and click the box many times until it is blank.
- Click Save.
For the detailed instructions, see Step 2 through this article: Undo And Remove Transactions From Reconciliations.
Also, I'd recommend reviewing your previous period's reconciliation. This will help us determine whether the opening balance for the current period is correct. You can follow the steps in this link: Fix beginning balance issues if you've reconciled the account in the past QuickBooks Online.
Once everything is in order, you can now reconcile your account. Check out this article for your reference: Reconcile an account in QuickBooks Online.
You stay connected with me if you have more questions about reconciliation in QuickBooks Online. Have a nice day.
