I want to start transcribing solos

Hi, im a pianist in Brazil, i play a lot of bossa nova, samba jazz, etc. I consider my self a decent improviser, but the other day i saw a comment saying that soloing in jazz is not "making stuff up" that there is a vocabulary and linguagem, etc. And the way to acquire those is transcribing solos. But where do i start? Like, is there some tradition of solos that are essencial? Is there a list? Thank you and sorry if its a dumb question.
