You were probably in the process of getting things switched and moved. Technically, you were probably a KS resident for part of the year. You can file MFJ as part year for each and only claim the income that is correct for that state and time period.
You might be able to make a case for KS nonresident if you had basically moved and established a new home in NY and were just in KS to finish things up. Having a home in NY, license, things that look like you plan to be a NY resident on Jan 1 could make you a KS nonresident.
