Is there a way to see the emails that have been sent to clients?

To verify your invoice details, we can check your email for a copy of the original invoice, lhconcreting.

By doing so, we can determine if you have enabled the Send me a copy option when generating invoices in QuickBooks Self-Employed (QBSE).

If you don't have it, you should request the original invoice from our client. This will allow you to see the description that was removed.

I've also attached this article for future reference in categorizing your transactions in QBSE to ensure the accuracy of your books: Categorize transactions in QuickBooks Self-Employed.
