Well..it depends on the details..
But, if you were already living in UT, tyhen went up to WA yo work temporarily for 3mos, then returned to UT....then NO you do not indicate you lived there.
They are asking if you had a permanent home in one state, then moved yourself and all your stuff to another state to live essentially on a permanent basis, to become a resident of that other state..and you didn't.
Instead, at the bottom of the My Info page, you would indicate that you worked in another state....EXCEPT that WA has no income tax....so in this case you don't even do that.
ALL your income, even the WA wages, are thus subject to taxation by UT.

It's fairly common for college students to head off for a few months in the summer, to work at a state/National Park, or at a beach. Some educators, with the summer off, go to another state to work temporarily for the summer. They really didn't move to that state....they are just there temporarily as non-residents.
