So you are saying there is indeed interest on the penalty amount itself. The penalty is actually over $900. So you would pay it with the tax return vs wait?
(note: still not sure why others recommended waiting for the IRS bill as if that would increase the probability of success for a FTA request. some others mention that one is likely to get an IRS bill/letter even if you pay the penalty with your tax return because the precise penalty/interest calculation by TurboTax is usually off a bit.)
