After you file

You are correct.  I found it couple days ago.  Long story short, I had a large minimum required distribution from my 401K in December resulting in having to pay large estimated tax in 4th quarter to cover it (which I paid).  TurboTax did not know this and assumed I owed interest and penalty.  I fixed it with tax form showing uneven income for the year so I ended up with a refund with no penalty/interest.  Thanks.
