How to calculate my Zerodha account Turnover for presumptive tax purpose

I want to make sure, my turnover do not cross 2 crore. I asked Zerodha support, they said, they dont provide any way to calculate turnover for full financial year, and the “quarterly” turnover seems to be bugged, it shows same value in all quarters.

What is the formula to calculate turnover for my current financial year? So once i reach 2 crore turnover, I can stop trading in that one account.
