Get your taxes done using TurboTax

I bought the Block sw for $34 on Stack.  I did most of my return and it suddenly said I owed $5000 where for several years with TT I got a $300 refund.  My income and other stuff has hardly changed, including my RMD's.  Perhaps I made some mistake but I don't know what.  I took my stuff to a local and very experienced and well recommended tax preparer who uses Intuit's professional sw and for her $250 tax prep service, I am getting back over $700.
