@nettynoo which state is this.. check state website if any sort of penalty waiver/abatements in effect e.g. disaster relief in NC.
if they recalculate your underpayment penalty independently like Fed does but have different information for 2023 tax info or estimated payments, they may get a different result than TT calculation. you should have a form in your state return with the penalty calculation you can go thru and see if there might be anything that state knows differently
