Showing effect of donation in itr-6

Sir / madam,

With reference to ITR-6, we have already shown donation in Profit and Loss account sheet. Another effect is in section 80G. Hence, the amount shown in Profit and loss account sheet need to be disqualified / reduced. Where should I give that effect? Either in Sheet OI or in the Sheet BP. Which section in applicable for such effect to nullify the double effect.

I will be happy if someone guide me in this matter.

Regards

Nishant
