To me, this (reporting these 72.15k gains as “tax-loss harvesting opportunity”) looks like a bug, since you don’t have to pay any LTCG tax on the 72.15k gains.
But : If you have LTCG from other sources (mutual funds, other brokers, etc.) that pushes your total LTCG to more than Rs.1L, then yes, you can use some of these unrealized losses to set off the gains above Rs.1L, so that you don’t pay any LTCG tax. However: whether this is beneficial or not depends on a lot of things (such as: where you expect the prices of the shares with the unrealized losses to go in the future), not just these numbers.
