Gstr 3b | ineligible itc

While filling the GSTR 3B, We had total ITC of 120,000 in this eligible ITC was 40,000 and ineligible was Rs 80,000.

In the box number 4 Part (A) line 5 we need to show full credit of 120,000 and reverse the ineligible in the part (D) line 1 of Rs. 80,000 under (As per section 17(5)). That time we well get the ITC of net 40,000/-

But we have mistakenly shown 40,000 in Part (A) line 5 and Rs. 80,000/- in part (D) line 1.

Can we rectify this mistake in the return GSTR 3B?
