Transcripts for CBSE Student, 12th Grade

I’m a student in CBSE, grade 12th (graduating March 2020), and am applying early for the Fall 2020 session at US Universities. Since I’m the only one applying from my school to the US, my Counselor (Vice Principal) and I are not super well versed with what documents to be sent.
What information must the transcript sent by the VP include? Should it just be report cards from 9th onwards till 12th midterms? Should it also include my academic achievements and standarized test scores? Besides these, an LOR, and School Report, is anything else supposed to be sent by the counselor?

Thanks a lot!
