as for what you lost in the scam. if it was a PONZI type scheme you can claim a casualty loss (an itemized deduction)
note that in the desktop version you must check the rev proc line right above the quick zoom for PONZI type scheme.
if you're not sure it was a PONZI type scheme check with a tax pro.
note this will only benefit you if loss and other itemized deductions exceed your standard deduction
you can not take a capital loss.
