Hello Andy!
When migrating data from QuickBooks Desktop to QuickBooks Online, you'll need to do it from the desktop interface. QBO is unable to use a backup file to import your data. I have a couple of options for you.
Option A:
Fix the freezing behavior in QuickBooks Desktop using the QuickBooks Tool Hub, so you can move your data to QBO. You can contact our QuickBooks Desktop Support if the issue is still not resolved, provided that the product is still a supported version (2020, 2021, and 2022).
- Click on Help.
- Choose QuickBooks Desktop Help.
- Choose Contact us.
- Enter a summary of the scenario and hit Continue.
- Click Message an agent.
Option 2:
You may ask someone in your area who has QB Desktop Pro or Premier to restore your backup. Then, move your data to QBO. You can find a ProAdvisor near you if you don't know someone who has QB Desktop. This is also an ideal approach especially when your files were backed up from a very old/retired version.
I'm just a comment away if you need more assistance with transferring your data to the online platform. Take care!
