I'm encountering a similar problem. I'm unable to sign-in to Intuit from the desktop application from the File menu on the app's ribbon or when I attempt to download 1099 data while using the desktop application. In all cases, the Intuit pop-up window remains a blank white box or it is greyed out, i.e., I can see it but it's opaque. The sign-on gives me the option of sign-in or register for a new account. Nothing works. I can sign-in to Intuit via a web browser with no difficulty.
