How frustrating!
I use the Desktop Platform, as well. Since the issue is signing into your Intuit account, let me make this suggestion. Under the "File" tab (far left on the task bar), the final option is to "Sign In". I believe that gives you the option to sign in to your Intuit account. Maybe you can sign in using that route, and stay signed in all the way through the import function?
Please post back if you continue to have difficulty.
