If you permanently moved, you will file a part-year resident California return that will report your California-source income, and a part-year resident Nevada return that will report your Nevada-source income.
In most cases, the source of income is determined by where you are actually living or working when the income is paid to you. There are a few exceptions. For example, if you own rental real estate or sold property, that income is sourced to wherever the property is located, regardless of where you live. (So if you sold a home in California, that will be California income even if the sale didn't close until after the move.)
Sale of other investments or IRA withdrawals are taxed based on where you live when the withdrawal was made. Even if the investment firm or broker is located in California, the withdrawal is taxed based on where you live when the withdrawal was paid to you.
Note that in Turbotax, you prepare your federal return first listing all your income. When you indicate you were a resident of two states during the year, Turbotax will prepare the part-year returns, but you will have to tell the program how to allocate each item of income to one state or the other. Turbotax won't automatically know which state to assign income items.
