it it was a Ponzi-type scheme then yes you can report the loss on form 4684 section for Ponzi losses. it will be part of your itemized deductions. you have to make certain selections
neither Tutbotax nor myself will be able to determine if it was a Ponzi scheme that qualifies for relief
instructions for Ponzi type losses start on page 7
