“The Schedule A asks for Miscellaneous:Other Subtractions ... so I'm thinking maybe it goes there - but how do you know for sure??”----> I guess you need to report your income in Kansas on Form 511 line 16; “residents are taxed on all income from non-business interest and dividends, SALARIES, commissions and other pay for personal services regardless of where earned. Wages earned outside of Oklahoma must be included in your Oklahoma return, Form 511, line 16; If you receive income for personal services from another state, you must report the full amount of such income on your Oklahoma return. As a full year resident of OK, you need to file your Kansas return as a nonresident of Kansas state on your Kansas income and you can claim your Kansas income tax credit on your home state return as a full year resident.
