yes super not comfortable submitting a return where i don't understand the number but i made every effort to reconcile this and the IRS publication 974 related to this isn't even available for 2020. So i went ahead and submitted it. Even if they approve the return (what are the odds they would catch it of the number is incorrect?) I still won't have an answer if the calculation was actually correct or if IRS is as confused by this circular relation of PTC and AGI as I am.
