It only appears that way. Almost every state "does it that way". They enter all your income. Then they enter you income sourced to that state and calculate a ratio to base the tax on. Follow the numbers on the form.
In TurboTax, you will reach screens where you allocate your income as sourced or not sourced in that state.
