Calculate the amount of net short-term capital gain (NSTCG) or net short-term capital loss (NSTCL). b. Calculate the amount of net long-term capital gain (NLTCG) or net long-term capital loss (NLTCL). c. Calculate AGI after considering the capital gains and losses. d. Identify if in any of the four situations there is a loss carryforward
