Underpayment penalty missing

If I did not have a 2110 form for my 2024 return (but I still had a 23K underpayment) and TurboTax did not compute any new underpayment penalty for the new 2025 tax return, then does it mean there isn't any penalty this year as well despite I underpaid by 31K? If not, what is missing? I did not apply for a waiver and both year TurboTax seem to not detect a penalty. How can I confirm if there is actually no underpayment penalty for both years?
