When I calculate my taxes I'm told that there is no underpayment penalty yet form 2210 shows up and says that I do. I had a home sale late in the year so estimated taxes to account for the home sale could not be anticipated, i.e., estimated. I can check box A in part II on 2210 to waive the entire penalty but then I'm told that I cannot eFile. Should I simply not file the 2210?
