Hi there, abbey2.
Let me help you locate and view the newly entered sales receipt.
QuickBooks Online (QBO) logs each financial transaction that is added, changed or deleted. You can view your Audit Log report by following these steps:
- Click on the Gear icon.
- Choose Audit Log.
- In the Filter drop down, set the date range.
- Under Events, mark to select Transactions in the Show only these events section.
- Click on Apply.
I've added some screenshots below, so you'll know what I'm referring to.

As a reference, here's a great article that will help: The Audit Log: What it is, how to use it.
That should do it. Leave a comment below if you have further questions. I'll be here to help.
