Problem is not a browser issue, its a TurboTax 2022 Deluxe bug. As mentioned in the original problem report, the user verified that TurboTax 2021 worked fine using the same browser. This is TurboTax trying to log into your Intuit acct for security purposes and the blank screen is supposed to have text fields for Intuit username and password. Actually sometimes the screen isn't blank - text fields appear for username/pwd, but you can't enter anything.
