@Sridharvsi , namaste ji.
Given the facts as iterated in your post --- I would hold still. Generally if the tax liability does not change ( Fed / State / FICA etc. ), then an amended return is not essential. Of course there are "ands. ifs and buts" to this. However, given that your change is only to Box 12, it would be safe to hold still -- if IRS wants more info , they will send you a note.
