Get your taxes done using TurboTax

Thanks, John!  Turbotax did a great job guiding me through the AI for the 2210.  Funny, I wasn't that far off doing my own quick-and-dirty method = here's what I made each quarter, here's what I owed, here's what I paid and then the penalty calculation.  I was off by $75.  But calculating the penalty myself will save me $135 - if the IRS agrees with the math!
