Hello jeansampson818, appreciate you for getting back to this thread.
There's one thing we can do when the CSV file is no longer supported in Quicken.
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.
Here are some of the links I've collected where you can get more tips and information about handling bank transactions and other help related to QuickBooks:
Let me know if you have done it successfully. I'm just right here if you still need my assistance with managing data within your QuickBooks Online company, jeansampson818. Bye for now and stay safe!
