Not able to reverse ITC in GSTR3B - 4(B)(2)

A user is encountering an issue when trying to reverse Input Tax Credit (ITC) in GSTR3B, specifically in section 4(B)(2). The field turns red with a 10% ITC warning. The user explains they need to reduce ITC due to claiming excess in a previous month. Another user suggests simply reducing the current month's claimed ITC, but the original poster questions if this is the correct procedure, especially given concerns about GSTR-2B accuracy.
