I think my first example works best for you.
You treat IL as a temporary stay as a nonresident.
In the TTX software you indicate you moved from CA to NV at the end of June. That gets you CA part resident return for Jan-to-end of June (~1 Jul)
Then at the bottom of the Personal Info page you indicate IL as a state you also worked in. that should get you the IL non-resident tax return.
Your company should have withheld IL taxes for May to end of June, since that is where you were e working from (if you told them so). Then they would have stopped IL withholding as soon as you told them you were now living in NV for July onward.
IL taxes just the May-1July wages as IL Non-resident. CA taxes all income from Jan -to-1 July as part-year resident, with a credit for taxes paid to il for those IL wages. Then no taxes for the rest of the year.
Each state (CA and IL) may tax you using a tax rate based on your total-full year income, but each should ratio it down based on only the income received subject to taxation by those states.
