Norton is almost like a virus in itself (as are many other anti-virus programs these days). Dump it with a complete and total uninstall and just use the free Microsoft stuff. My guess is that Norton is blocking stuff that is preventing TurboTax from properly functioning.
I'm a software developer and run into stuff like this a lot when people try to use my software. All you really need is to be smart and use the free Microsoft antimalware stuff included in Windows 10 and 11.
