The only thing that I'm changing is that the original return used the short method for estimated payments due and averaged my tax liability evenly over each payment period. In doing so it calculated that I owed a underestimated tax penalty. Since my income varied greatly in Q4, I filled out form 2210 with the annualized method and no penalty is owed. TurboTax doesn't show the penalty on column A of form 1040X so it's not making an adjustment in column B so that I can get the penalty refunded. I looking for help on what I need to do to get TurboTax to take into account the penalty on the original return.
