This is the first year I have ever had to fill out form 4952 for Investment Interest Expense Deduction. Can someone explain to me the difference between line 4d and 4e? for the year i had a $12,000 short term capital loss and $0 long term capital gain. Would the 12,000 loss go on line 4d and $0 long term gain go on line 4e? Any help would be appreciated.
