Deductions & credits

In a follow up to my investigation of this issue I did a search on this platform on the question: 

Court Judgment Bad Debts, and I note the Best Answer posted by JulieR on a artist works sold by dealer and her reply that appears to reinforce my observation on if this loss of mine may be deducted and if so how to enter in Turbo Tax.  Again, thank you for your review and input.
