@pk
PK thanks for the valuable feedback.
This is for my dad who is a NR, and you are right we erroneously filed 1040 for him via Turbotax in the past couple of years. He was living and working in the US since 2014 and used the home as a primary residence, when he moved out of the country in 2017 (Canada) it became a rental property. Thanks so much for the feedback the best for him seems to reach out to Sprintax or another expert to file this year to get this matter resolved.
[I personally use Turbotax as well, but reside in the US hence how we got to the forum]
Thanks!
