client is MFS does not know how husband filed. (as far a itemizing ) she has gambling  in of excess $2million dollars, losses of less the $2 million with a small gain of about $9,000.  I am not sure how to handle this. Can I list the losses even if she does not know if he took standard deduction. In previous years they filed together so it wasn't a problem.  Thanks for any advice you can give me
