Deductions & credits

Thank You HACKITOFF.  Can you be a little more specific please?  On Schedule A, which block do I put my total ponzi loss?   I can amend my 2018 tax filing no problem.  I have losses that should carry forward for 4-6 years and would hate to loss that as I already got a major hose job dealing with the ponzi.  There are many of us victims in the same boat and will share your info.  Thank you again
