It can be concerning to have invoices go missing. I appreciate you Amya, ChiColor, and Aes for letting us know about this. You concern about this matter is understandable. 

Upon checking here, we still have an ongoing investigation (INV-115473) where customers like you are unable to view new money in/out transactions in search or recent transactions.

Please be assured that we are taking your concerns seriously. Our dedicated product engineering team is actively working to examine it and develop a comprehensive solution.

To be added on the list of affected users, I suggest contacting our QuickBooks support team. This way, you'll receive an email when this will be resolved.

Here's how you can reach them:

1. Head to the Help icon, then the Search tab.
2. Type in Contact Us in the search bar.
3. Click Contact Us.
4. Choose the Chat or Callback option.
    

In the meantime, we can run an invoice report to view all the invoices you created. Doing so will ensure we can check if there are any duplicate transactions, Amya. Here's the step-by-step guide:

1. Head to the Reports menu, then enter Invoice List on the search bar.
2. Set your preferred Report period.
    

Once you've received a payment from your customer in the future, you can record it in QuickBooks to mark the invoices as paid.

We appreciate your patience and understanding as our product engineers diligently work to resolve the issue. We are committed to ensuring everything is sorted out as quickly as possible. If you have any other concerns or questions, reach out to us without hesitation.
