Income tax return form selection

Dear Members,

I have earning of short term capital gain by selling of listed shares of Rs 2.45Lakh during FY 2020-21 and AY 2021-21. I have no other income. The trades are from savings. I need to file income tax return for record. I have confusion to which relevant ITR form to choose i.e. ITR1 (as no liability under STCG) or ITR2.

Furthers the NSDL reporting showing higher amount in annual reporting portal while actual earning is lower as per the capital gain statement of the service provider. I have 5000 speculative income on intraday as well. Can I avail 80D deduction ? so it allowed to bring down the basic exemption limits.  Thanks with regards, Vijay
