@Thanh Ly you must first complete your federal return, then your non-resident state which is CA, only then will you complete your NV return.
It can be very complex what income is taxed by CA as it depends on so many matters.
If you lived in UT and worked for a company in CA it would be all your income.
Please just utilize TT and these forms will fill in for you if you complete the returns in the correct order.
Good luck
