I wish I could make it better, @James112.
Since you received an email saying you're still unable to convert your data from the desktop to the online version of QuickBooks, I'd recommend contacting our Data Services Team.
With their tools, one of our specialists can help you successfully convert your company data. To contact our dedicated support, you can use the following instructions outline in this article: How do I contact QuickBooks Data Services?
On top of that, I've also included this reference for a compilation of articles you can use while working with us: Get started with QuickBooks Online.
If there's anything else that I can help you with, please let me know in the comments below. I'll be here to lend a hand.
