Pega is restricting this wrap text check box only to freeform layouts for textInput. This option is not available for Dynamic Layout as Dynamic Layout will adjust with screen display area and will automatically handle the wrapping of data. This is as per UI design.
If you still want it then you have to choose free form layout to get this option instead of dynamic layout.
