I understand what you are saying... that was why I was hoping TurboTax experts would know how to treat this. They told her to file as a resident of WA for those two months and she wouldn't have to worry about the Kansas impact. (I wasn't at her orientation so trusting what she remembers. 😀) Something just seems wrong that a 20 year old would be paying thousands in state taxes because the company underwithheld state taxes in a state that didn't have them. (They grossed up for federal purposes so she is ok there.)
