How do I delete a reconciled account and start over?. I did it before but forgot the steps. I remember that I added myself as an accountant, that gives privileges.

I'm glad to see you here in the Community, @miner_tom.

The Undo option for a reconciled period is only available in QuickBooks Online Accountant (QBOA). Since you've mentioned that you've added yourself as an accountant. You'll need to log in using your QuickBooks Online Accountant to undo the reconciliation. 

Here are the steps to undo a reconciled account with QBOA:

1. Sign in to QuickBooks Online Accountant.
2. Go to the Clients list.
3. Find your company and open QuickBooks Online account.
4. Go to the Accounting menu and select the Reconcile tab.
5. Click History by account, then choose the account you want to reconcile and date range from the drop-down menus.
6. Find the reconciliation on the list.
7. If you haven’t already, tick View report to open the Reconciliation Report. Review any discrepancies and changes your client wants to make.
8. When you’re ready, click the arrow in the Action column, and then pick Undo.

Once done, to redo your reconciliation you need to go back to your QuickBooks Online (QBO) account.

Here are the steps for reconciliation: 

1. Go to Settings and then select Reconcile. If you're reconciling for the first time, select Get Started first, and then Let's do it.
2. From the Account dropdown menu, choose the account you want to reconcile. Make sure it's the same one on your statement.
3. Check the Last statement ending date. Make sure your bank statement starts the day after your last reconciliation.
4. Review the Beginning balance. Make sure the beginning balance in QuickBooks matches the one on your bank statement. Here’s what to do if they don't match.
5. Enter the Ending balance and Ending date as they're written on your bank statement. Some banks call the ending balance a "new balance."
6. When you're ready to start, select Start reconciling.
