Both my wife and I have unused tuition and education carryover that we'd like to transfer to our parents. I'm given the option to do so but my wife isn't; why?

Did your wife enter tuition for 2022 or is it all carried forward from previous years? You can't transfer tuition that has been carried forward.

That answers it, my wife's is carried forward from previous years. Thank you @TurboTaxSusan!
