Do I have to amend my state return if I amend my federal return? (Oklahoma)

I'm editing the box that states I can be claimed as a dependent to I CANNOT be claimed. I was not claimed and am not editing any numeric categories on either return. I didn't see a need to edit my state return but Turbo Tax automatically suggests I amend my State return and won't allow me to only amend federal. According to the explanation for some reason I have to submit my amended returns physically in Oklahoma ( if I understood correctly?). Last I heard the IRS wasn't accepting hard copy returns so how am I supposed to do this? 1. I don't even need an amended state return and 2. This state block would make it impossible to file my amended federal.
