Q. Is it also correct that the standard deduction for part-time filing in the state I worked is prorated to only the time lived in that state? Or can I request the full standard deduction?
You can't ask a question like that, without identifying the state you're dealing with.
That said, the standard/generalized answer is you get the full standard deduction. But the standard/generalized rule is also that tax is calculated on your full year income and then a percentage is used to calculate the amount allocated to your in state income.
