Thank you for getting back to us, @Migrating to On-Line Problem.

I can help you with exporting from QuickBooks Desktop to QuickBooks Online. 

Can you tell me more about the version of QuickBooks Desktop (QBDT) Premier that you're using? You need to have the desktop updated to the latest release to move your data to QuickBooks Online (QBO). You can follow the steps outlined by Jen_D above.

For more information on how to get your desktop file ready and move your data to QuickBooks Online, check out this article: Move your QuickBooks Desktop file to QuickBooks Online.

After getting your data from QuickBooks Online (QBO), here's how you can set up your QBO account, manage your users and their access, and many more: Get started and adjust settings after you sign up for QuickBooks Online.

Let me know in the Reply section if you need further help exporting your data from QBDT to QBO. Keep safe, and have a wonderful day!
