reconciled acct. then found double entry of expense deteleted now what.

Thank you for reaching out and letting me know about the reconciliation and the double entry situation you've encountered, @Beth Anne West. Great job on noticing and deleting the duplicate expense entry. I'll share some tips on what you should do next.
 

First, re-verify your account balance to ensure it reflects the correct amount after deleting the double entry.
 

1. Go to the Chart of accounts.
2. Find the account on the list.
3. Select View register.
4. Search for the opening balance entry. It should have "Opening Balance Equity" in the Account column.
5. Take note of the date and balance.
    

Refer to this guide for more detailed info: Fix issues the first time you reconcile an account in QuickBooks Online.
 

Next, update any financial reports that were affected by this mistake. Also, look through other transactions to make sure there are no more duplicates.
 

After that, I recommend doing another reconciliation of the account now that you've fixed the error.
 

If there's a need for you to undo or remove transactions, I suggest consulting with your accountant or you can get assistance from QuickBooks Live Experts.
