Having the same issue. I get the white screen when trying to access Fidelity 1099 import or from the File -> Sign In drop down. In both cases when I select "I already have an Intuit account", I get the white box. I'm using a SurfacePro 8 with Windows 11 Home. I've been able to import 1099 from other institutions that allow sign in directly from TurboTax. Clearly this is an issue TurboTax.
