Get your taxes done using TurboTax

Some individual with nothing better to do found a way to get ito my PC claiming it was Microsoft even with a nice logo.  They did something which removed my prior year's Turbo Tax data file so normal transfer routine will not work.  I filed my returns electronically and I am wondering if Intuit, Federal IRS or State maintain anything which would assist me.  Yes, I should have backed it up on an external drive; a big mistake on my part.    The water is now over the dam and the cows are loose.  What can I do?
