Authenticator enabled but NOT working for login

2FA apparently shut off automatically after Google Authenticator enabled. All subsequent logins (with empty cache to ensure no cookies) fail to invoke Authenticator, reducing login security to password-only. Why?

TT online automatically disables 2FA (called "2-step" by TT/Intuit) after Authenticator is enabled; this is a coding error. Unfortunately, TT also has an infinite loop on "Continue" when trying to re-enable 2FA if the code is to be sent via voice phone call (as it should be since clear-text SMS has been deprecated for many years and is a serious security risk). However, the path to reset login security does NOT have this bug and, once 2FA is enabled again, then Authenticator works as expected, with Authenticator flagged as "primary".

BOTTOM LINE: TurboTax/Intuit requires both settings to be enabled.
