Hello, @rjmihelich.

Let me share some information about missing attached documents in QuickBooks Desktop.  

When using QuickBooks Attached Documents, an Attach folder is created and stored in the same location as the QuickBooks company file. Renaming or moving the company file to a different location will break the connection between the Attached Documents and company file.

To fix the problem, re-link the Attached Documents. Here's how. 

1. Browse to the location where your company file is stored and open the Attach folder.
2. Open the folder with the OLD company file name.
3. Copy and paste the contents of the Inbox folder into the Inbox sub-folder of the folder with the new company file name.
4. Copy and paste the contents of the Txn folder into the Txn sub-folder of the folder with the new company name.
5. From the QuickBooks Company menu, select Documents then Repair Attached Documents Links.
6. Select Repair Links.
