Get your taxes done using TurboTax

TurboTax calculates and includes any underpayment penalties in the shown "Federal Tax Due": "The balance due on your return includes this penalty." I believe to @DoninGA's point above this does not include failure to pay penalties. The penalties in the screenshot below only covers the category of failure to pay proper estimated tax.

See TurboTax desktop > "Personal" tab > "Other Tax Situations" > "Additional Tax Payments" section > "Underpayment penalties"
