Can I fill in Form 2210 to avoid underpayment penalty (4th qtr Roth Conversion and estimated tax payment) even though TurboTax decided I don't need to see the form?

My Roth conversion was in December 2024 and I made an estimated payment before January 15 2025 to cover the taxes. I understand that I could still face underpayment penalties unless I use Form 2210 to declare how much income I had in each quarter because the IRS doesn't have the dates and can assume I received the income throughout the year and underpaid for early quarters. I tried to go to the underpayment section of Other Tax Situations but wasn't presented with the form information. Just a statement that "At this point no underpayment penalty applies to your return." Is that reliable?

Yes, that's reliable. TurboTax has determined that you paid enough to avoid a penalty, regardless of timing. Therefore you do not use Form 2210. If you started to fill out Form 2210 you would reach a point where it tells you "Don't file Form 2210."

Thanks for the reply.

If that turns out to be wrong (or contradicted by the IRS), does the guarantee include TurboTax covering any penalties their mistake caused, or otherwise helping me avoid penalties with the IRS?  I'm a bit hesitant to actually file without knowing that.  It's frustrating to not be able to provide the information that might be helpful to prevent an issue in advance.
