Desktop to Online

Hi there, Anne911. 

I'll make sure you'll be able to import data from QuickBooks Desktop to QuickBooks Online. 

Let's perform a few troubleshooting steps to determine the reason why you're unable to upload your company data to QuickBooks online.

To begin, let's use the Verify and Rebuild tools to self-identifies and self resolved the most commonly known data issues within a company file. To proceed, please see the steps below:

1. Go to the Window, then Close All to close all open QuickBooks windows.
2. Choose the File menu, and then select Utilities.
3. Click Verify Data.
4. Then, go back again to Window, then Close All to close all open QuickBooks pages.
5. Click File, and then Utilities.
6. Select Rebuild data.

I've added this article for more information:  How to resolve issues when importing.

Once done, restart your desktop first before working again with QuickBooks. Then, right-click on the QuickBooks icon on your Desktop, select Run as Administrator, and move your company data accordingly.

Additionally, I've enclosed some resources below to learn more about converting data in QuickBooks:

Keep me posted if you still have questions or concerns about moving transactions from QuickBooks Desktop to Online. I'm more than willing to help. Take care and have a nice day ahead.
