Information in my ds-160 is entered wrong and my OFC is already done. How do i correct it?

Could someone please help me here… i’m applying for f2 dependent visa and made a mistake in ds-160 form. In place of principal applicant’s name and principal applicant’s sevis ID, i gave my details(dependent’s details were given instead of F1 holder’s). My OFC is also done on last week and i have my interview scheduled on 19th of May(i have only two days left). What should i do now? How do i correct it?

Complete another DS-160 form and submit it. Then carry new DS number to your interview and request the person to either replace old DS# with the new one, or update the details in the old one.
