Hi Sarah,
It's good to hear from you again. I'd be happy to share more info on this.
If you'd like to edit a reconciled transaction, you'd have to unreconcile it first so you can edit it. Here's how to unreconcile in QuickBooks:
1. Select the Gear icon on the Toolbar.
2. Under Your Company, select Chart of Accounts.
3. Locate the appropriate account for the transaction.
4. From the Action column, select Account History.
5. Identify the transaction to edit.
6. In the reconcile status column (indicated by a check mark), repeatedly select the top line of the transaction to change the status of the transaction.
Codes indicate the status of the transaction:
C - Cleared
R - Reconciled
Blank - Not cleared or reconciled
7. Select Save.
