My 1099-B is from Vanguard and at the bottom of the form it says, "For securities sold that were acquired on a variety of dates, Box 1b may be blank." So I'm thinking of changing my answer for box 1b to "Various (or more than one date)". Anyone think this will be a problem? It doesn't seem any more dishonest than manually entering a random date that's more than 1 year old.
