I used the "Stash" app to invest, and now am trying to file my 1099-B. Is there a way to import it, or must I try and figure out what to put where myself?

I am right now trying to enter in my 1099-B from "Stash" and am trying to enter it in, however there is a lot to enter and I do not know what is needed to be entered in. Is there a way to import it or at least help me figure out what is needed more clearly so I do not have to figure it all out step by step on my own?
