Over the past several months, I have posted expenses to A. Smith. Now I found out I have to post those expenses to A. Jones. How do I credit the expenses for A. Smith? These items have already been reconciled. Not sure how to make

I understand that you want to keep your expense account accurately recorded in QuickBooks Online, zoeann. Let me guide you through the process of correcting your expense transaction and putting it in the correct account.

If your transactions are check and expense, you can edit the payee information directly from your Bank register. This way, you can easily move the expense from A. Smith to A. Jones.

Here's how:

1. Go to Transaction in the left panel, then Chart of Accounts.
2. Look for the bank in question and click on  View register.
3. Click the expense/check transaction.
4. In the Payee field, choose the correct vendor.
5. Select Save.

However, we need to unreconcile it first if it's a bill payment. 

Here's how:

1. Go to Transactions, then Chart of accounts.
2. Choose the account you're working on, and click View Register.
3. Select the bill payment you want to unreconcile.
4. Keep clicking R status until it shows blank or cleared (C).
5. Click Save
6. Tap the bill payment again and hit Delete.

After that, open the Unpaid bill report to check the bill and change the Vendor/Payee. 

Here's how:

1. Type "Unpaid bills" in the search bar.
2. From the report, click on the bill that you want to change.
3. Select the Vendor field and choose the correct vendor
4. Click No to the pop-up message.
5. Tap Save.
6. Go back to the Bills and Mark as paid.
7. If everything is correct, reconcile again for bill payment.
