I'm joining this thread to provide additional information, Tanswork.
While waiting for your response regarding the follow-up questions raised by SIAB, please be aware that we have encountered this issue with company files that have payroll enabled. Can you please confirm if you use payroll in QuickBooks? This will help me provide accurate solution to your concern.
You can transfer data from QuickBooks Desktop's old version to QuickBooks Online using an online tool. Go to this website and select the link for your QuickBooks version. Then, follow the steps provided in this article based on the QuickBooks version you have. This process applies to the US region.
Since you're using the international version of QuickBooks, please note that QBDT isn't offered in South Africa. Therefore, there's no option to automatically migrate from Desktop to Online. I recommend exploring third-party applications that can assist in converting your files between the two programs.
After that, you can refer to this article for steps on how to import data to QBO: Common questions about importing data to QuickBooks Online.
