Hello @E40Katie,
As of the moment, there isn't an integrated way of exporting your data in the cloud for two different versions of QuickBooks. A company data from a desktop version can only be exported to the cloud and work with it on a desktop app.
Instead of utilizing the export function, you can invite your accountant from QuickBooks to do the accounting of your books. If you wish to proceed, here's an article you can read for the detailed instruction: Invite an accountant to review your accounting in QuickBooks Online.
Additionally, I've also included this reference for a compilation of articles you can use while working with us: Know where you stand financially.
If you have any other questions, please let me know by leaving any comments below. Stay safe!
