This is what the instructions say.
In Column B, enter the amount of Column A received from state sources or income received while a resident of that state.
So it depends on how you interpret it. If you are looking at the first part of the sentence, the state rental income = $4000
But if you look at the last part of the sentence, since you were never a resident of that state = 0.
See how confusing it is? Someone else understand this?
