Thanks for the response, @MyTaxTutor.

It sounds like the reconciliations from your QuickBooks Online didn't export into your QuickBooks Desktop. I recommend trying the export from QuickBooks Online to QuickBooks Desktop one more time. During the process, I'd leave your computer alone and not run anything besides the program. This minimizes the risk of any errors to occur. If the issue persists, please don't hesitate and reach back out to me.

Let me know how this goes for you! I'll keep an eye out for your response.
