A user mistakenly entered IGST, SGST, and CGST input tax in the RCM input column of their GST 3B. They are not an e-commerce operator and need to know how to reverse this incorrect entry. The advice given is to reverse the wrongly claimed RCM input in the next month's GSTR 3B under the 'other reversal' row and claim it in the correct place. Alternatively, they can reduce the RCM input claimed in subsequent periods by the wrongly entered amount.

You means it was no pertaining to RCM ITC? if yes. then in the next month 3B, you can reverse the wrong one and take it in the correct place.

You have to show it in other reversal row. Let the credit appear in that column. Another thing you can do is when you have RCM credit in next periods then you shown less credit(by this wrong amount shown now) in RCM ITC row.
