fulltime remote work for NY - shouldn't be paying state tax, but turbotax....

Hello - I started working remotely for a NY institution last year.  Never once stepped foot in NYS (live in Tennessee) and it's at the convenience of my employer.  Yet when I fill out a non-resident return, I'm taxed on my income from the NY source.

 

That seems incorrect according to 132.18(a) and numerous discussions that I've read here.   How do I get Turbotax to respond to my situation correctly?  (Have ticked off every non-resident box in IT203, but maybe there is something more).
