So, did you make quarterly estimated payments over and above your withholding? If not, then this won't apply to you, but sometimes I've found if you look at the estimated payments worksheet where is shows when you paid your quarterly payments and how much, TurboTax gets this wrong and if you adjust the payments and dates, the penalty is no longer relevant because now TurboTax knows how much exactly you paid each quarter and stops assuming you paid the same. This would apply if you earned a big bonus or some income one time during the year and paid extra taxes at that time to cover it. Anyway, as you mentioned, it is $2 so not sure how much effort you are going to put in to figuring out where the calculation is going wrong. I have seen some people saying their penalty is over $450 and they are getting a refund! Not sure what is wrong there but hopefully they can get it figured out.
