Happy to have you here in the Community, @na.midoffice. Let’s make sure that all data are exported from QuickBooks Online (QBO).

The export feature in QBO allows users to easily save the information you've placed into your file to your hard drive. To obtain the missing data, I suggest you double-check your QBO account to see if the data you're looking for is there. Also, make sure that the range of dates is properly selected before exporting it again.

Once done, you can utilize this article to see the step-by-step process of exporting data and other transactions from QuickBooks Online: Export data, reports, lists, and more from QuickBooks Online.

Feel free to add a comment below should you have any concerns with transactions. The Community always has your back. Have a great day!
