Additional Income due to Identity Theft

I was a victim of identity theft and it resulted in a fraudulent redemption of mutual funds and other losses from bank accounts.   I not only lost the funds from the mutual fund redemption but the 1099-B I received from the mutual fund management company with the short and long term gains  results in $6000-7000 additional taxes now and $2000-3000 in additional Medicare premiums next year.  How do I report this?
