I'll help you resolve this receipt forwarding concern, Dal.

We don't have a way to know which client the emails belong to immediately. But you can check each of those emails to figure this out. 

Don't worry, I know how to fix this going forward. Let's change the email address that your QuickBooks Online uses to send receipts. 

Go as follows: 

1. Go to the Banking tab and select Receipts. 
2. Select Forward from email.
3. Hit Update, then enter your email address and click Confirm Change.
4. Follow the on-screen instructions. 

Once done, re-send the receipts, and the data will go to that customized email. 

In addition, if you want to give users permission to forward receipts, you can check this article for complete steps: Email receipts and bills to QuickBooks Online.

I've included this guide that contains steps to review, edit, and match those uploaded or sent images of receipts and bills to avoid duplicate transactions: Capture and categorize expense receipts and bills in QuickBooks Online.

Get back to me if you have further questions about receipt forwarding. I'd be happy to help you. Enjoy the rest of the day!
