I appreciate you for getting back on this thread, @VentCare.
I'll join this thread and address your concern to help you manage your files.
If you're considering looking for a third party that offers conversion services and helps you move your data from QuickBooks Desktop (QBDT) to QuickBooks Online (QBO), I recommend reaching out to your app's Customer Care Team. This way, one of their representatives can guide you on the best process for managing your downloads.
For a visual reference in importing your data to QBO, check out this article: Common questions about importing data to QuickBooks Online.
Once everything is all set, here's a great resource that can guide you further in getting started with QuickBooks Online: Getting Started With QuickBooks Online.
Feel free to visit here again in the Community, and keep me posted if you still have more queries about data conversion. I'm here to help in any way I can. Keep safe always.
