You can not submit revised return u/s 139(5) since it was a belated return u/s 139(4). Please check ITRV and see if the fathers name has been taken from PAN database or it is the wrong name which was erroneously mentioned in the return. If there is wrong name you need to wait for the return to be processed and wait for communication from CPC.
