Let me step in and assist you in exporting your data.
The Task List only shows on your dashboard once you have a pending task. However, if you received an email that notifies you to complete the task, you can perform basic troubleshooting to see if it's a browser issue or not. This way, you can clear the outdated file that causes a small problem with your bank feeds.
Please open your QuickBooks via a private browser.
Here's how:
Google Chrome: Ctrl + Shift + N
Mozilla Firefox: Ctrl + Shift + P
Safari: Command + Shift + N
Microsoft Edge: Ctrl + Shift + P
Then, check your task list on your dashboard. If you're able to do so without any errors, you can switch back to the main browser to clear the cache. You can also try using other browsers to isolate browser-related issues.
