WRONG ITC

I wrongly claim and c/f IGST 74000 in jan month. No tax liability. Also not adjusted in Feb month. In March 3B filing i want to reversal this amount and to be shown in 4B2..Is it correct or not.

But no eligible itc in March. And no tax liability in march. So it shows net itc negative balance. Can i file with this negative balance to reduce the balance in GST ledger Or any other steps..Pls clarify

Thanks in advance
