What is the correct state source(s) of income for mineral rights? (See added details)

I live in Kansas and in 2018 I received mineral rights rents and royalty income from property located in Oklahoma. 

 On my federal return Turbo Tax processed the rents as other income in Schedule 1 and the royalty income in Schedule E.

 I get confused when it comes to determining the “state source of income” so my question is do I have to report and pay taxes for the rents and royalty income in (1) Kansas only, (2) Both Kansas and Oklahoma, or (3) just only in Oklahoma?
