If I sell Shares within 12 months of buying, I understand it is considered as STCG and I should pay 15%. But should I pay it as advanced tax at the end of that quarter or can I pay at the end of the year?

I got SMS that I need to pay advacned tax by 15th Sep but not sure I should be paying it. If it is all legal and I can by the end of year (without any penalty), I would like to do so.. Please give your opinion..
