We'll see what happens. I tried to use worksheet P and X in publication 972 to confirm the number turbo tax spit out but my head literally exploded trying to follow the iterative process to reconcile premium tax credit with AGI limit etc.
So in the end I went ahead and submitted the return with the number turbo tax entered. I really don't think that number is right since it's about 2x the amount of health insurance premiums we paid. We'll see what happens.
