I will also comment here that TurboTax should allow you the option of declining to include a penalty. If the IRS thinks you owe a penalty, they will calculate it according to their own formula and send you a bill. Even if you allow TurboTax to calculate the penalty, the IRS will still re-calculate it, and may still send you a bill for any difference if they calculate the penalty differently. Also, if you do get the bill for a penalty, there is a procedure to request an administrative waiver or abatement if this is the first time you have ever owed a penalty. (It’s harder to request a waiver of the penalty if you’ve already paid it.)
