You need to link up your approved EB1A I-140 petition with your pending I-485 application by requesting that this approved petition be "interfiled" with your pending I-485 application. At the same time, I would recommend that you ask your local U.S. representative to make an inquiry with USCIS (something that is done all the time) and that you also submit a "service request" through the USCIS website regarding your pending I-485 application.
