I'm happy to assist you in changing the dates on your previous transactions, @merionmsharp.

We can directly change the date as long as your books have not been closed yet. If it's closed, we'll need to supply the closing password.

Before we proceed, may I ask what kind of transaction are you trying to change the date? You can follow these steps to locate and change:

1. Go to the Magnifying glass.
2. Search for the transaction you want to edit.
3. On the Date box, change the date you want.
4. Click Save.

Moreover, let me share this article to assist in reviewing your transactions: Find, review, and edit transactions in account registers in QuickBooks Online.

Let me know if you still have questions about your transactions in QBO. Have a lovely day.
