Adjustment of Status - I-485

interview date was 08/01/19,

in the interview that officer discovered that I was put myself as married when I applied my F-1 visa in sept 2014. But I already got my divorce cert on 04/20/2014. how to remedy this situation?

and I also forgot to mention my previous marriage on my I 485 application that one also discovered. I just found it out the day before the interview and decided not to say it when officers asked have I ever been married before? I said no. Now Im in hot mess. good thing is I already divorced from before to marry my current husband.
  
 My advice if you made mistake on your I 485, just admit it to the officers instead of hiding it. don't repeat my stupid mistake.
