401k contribution in TurboTax indicates our max is 15k

My wife and I are both over 60 years old, both working. She contributed 30k to a traditional pretax 401k; I am an HC employee and contributed 22,500. However, TurboTax (filing jointly) is calling out that our limit is 15k and flagging a potential penalty and a need to withdraw the excess contribution. 

 

Have I selected an incorrect option, or is this a software issue?
