When people post answers they really need to specify whether using Online Turbotax or desktop and for desktop indicate windows or mac, not sure for desktop if there is a difference.
The desktop doesn't have/show whatever people had said before to go to and hit delete.
I use desktop Mac and at the end when I efile, I just uncheck the file for WA and will file later. Since I am part year resident of NC and live in WA now. I had to download NC to file non-resident and never downloaded WA since I didn't need it.
