After you file

The exact same thing happened to me, I was just surprised to receive this notice from the IRS.  I think possibly as intuit continued to update the software maybe they added in more questions, but I do not remember being asked about deferring my taxes at all.  This is really annoying and I am sure for some people will be a real burden or hardship.  Why doesn't turbotax mention anything about this in the summary information, it let's you know about estimated taxes for the next year, but not that you are going to owe a bunch of money at the end of the year also???  I have used turbo tax for years, this was handled poorly.
