Appreciate the complete details of your concern, @newolduser.
Allow me to furnish you with information on how QuickBooks Desktop handles your QuickBooks Online company file when undergoing the conversion process.
When exporting your QuickBooks Online information to QuickBooks Desktop, there are some information that will not be included. Reconcile reports, due to their special nature as a static report, are not exported.
For a more comprehensive list on the limitations of exporting process, you may check out this article: Export limitations - QuickBooks Online to QuickBooks Desktop.
