Thanks for the reply. Yes, I am able to find it, but what is confusing to me is that, it requires two numbers:
(1) Schedule D, line 15 Net long-term capital gain or (loss)
(2) Schedule D, line 21 Allowable loss
But if Schedule D, line 21 is non-zero, then nothing can be carried over to this year. But I think this is wrong, because if you look how Schedule D, line 21 is calculated, it's just max of $3000 and line 15 Net long-term capital gain
I think it's a bug in TurboTax software
