state franchise tax board says never filed for 2022

State franchise tax board recently asked my husband for a copy of his (really it's our) 2022 return that we filed with turbo tax on a Mac. We sent them the fed and state returns pdf that was generated with turbotax mid-april 2023 -it showed we had gotten a state refund of about $600.

 

they sent him back a bill  for a few hundred, mostly charging him (I am not involved somehow) for filing his taxes late.  It also says that state return submitted had a mistake --and our refund is, they say, less by $50 and so we owed interest on this $50 as well as the late filing.  (State franchise tax board seems to be saying  both that the state return was never filed AND simultaneously that we got a return that was $50 high.)

 

How can we get proof that we filed via turbo tax (do have an e-filing  receipt from turbo tax but it doesn't really say whose/which return) ?
