Hello, @jerrym.

I really want to help you locate the transactions with serial numbers, however, the only way to do this is to go through each transactions using the reports provided by my colleague. 

I'd suggest reaching out to our Desktop Specialist again and provide them with your case number. This way, they can look into this thoroughly and escalate the issue if needed.

I'm sure this will be taken care of. For other related articles, you may need in the future, you can visit our site for help: Articles for QuickBooks Desktop.

Please keep me posted how the call went. I'll be on the lookout for your reply and help if you need anything else.
