We can look for a third-party application that allows you to bring your data from Quicken to QuickBooks Online. There are a number of applications that we can use. However, we're unable to recommend one. I'd recommend clicking on this link: QuickBooks Apps Store. From there, browse and search for any application relevant to your needs. Before you get the app, I'd recommend checking the application's Overview, Pricing, Reviews, and FAQs. Once done, you can click the Get app now button.

Keep in touch if you need any more assistance on \exporting your data, or if there's something else I can do for you. I've got your back. Have a good day.
