yes, it's such a big deal. I think what Tax Act guarantees you is a "max refund" which isn't much of a liability to them. TT guarantees something entirely different - accurate tax calculations. That requires a lot more complicated software testing to be sure the many complexities of treaty-based positions are up to date, and honestly, it's not really possible to manage - every single tax treaty as its own set of rules and provisions.
The vast majority of filers trying to do their own 8833 are probably messing up their returns, anyway, and TT is right to steer clear of that enormous potential liability.
TurboTax doesn't just not support this form for e-file, they do not support it at all.
