I'll guide you on how to export your data from QuickBooks Online (QBO) to QuickBooks Desktop (QBDT).
Currently, Internet Explorer (IE) is no longer supported by QBO. This can be the reason you're having trouble exporting your data.
However, exporting your data will still work by accessing your file into this link in IE: http://qbo.intuit.com/app/exportqbodatatoqbdt.
Once done, you can follow the steps below to complete the process.
To learn more about exporting your file from QBO to QBDT as well as its limitations, you can check out these articles:
