Query about STCG tax is charged

Hi everybody, I am new to investing, I started working 2 years back and my income is hovering around 8 LPA this year it might go to 8.5-9 LPA maybe including variables. I put some of my money into gold and silver ETFs and now my profits from both of these are nearing INR 1 lakh. so I have a query that will the STCG be automatically deducted from profits when I sell the ETF shares? I do not file ITR till now, so I'm not aware about taxes that much. Kindly enlighten.
