Hi llcc!

Thanks for joining this post. Allow me to assist you with attachments in QuickBooks Desktop.

The link in the previous reply is from the old QuickBooks Community platform. We're unable to access it which is why you encountered such an error.

Currently, QuickBooks Desktop doesn't have a report that shows transactions with or without attachments. You'll want to manually open and check each transaction. If the Attach File button has a number, it means it has an attachment on it.

Also, I understand that you need to review the attachments in QuickBooks Desktop. While there's no report about this, you'll want to send feedback to our developers and let them know that you need one. Go to the Help menu, select Send Feedback Online, then Product Suggestion.

Lastly, note that you can always go to the Company menu, select Documents, and then Doc Center. From there, you'll see all your attachments.

I added this link that answers the common questions about Doc Center: QuickBooks Document Center: FAQs and common issues.

Post again here if you need more help with this. Wishing you all the best!
