How did the Anderson vote break down in 1980?

It's impossible to know for sure, and the specific question of who Anderson voters would've voted for if he wasn't on the ballot wasn't asked in the exit polls.

About the best way to extrapolate is from the ideology question. 11 percent of self-identified liberals voted for Anderson, compared to 4 percent of self-identified conservatives. So I think it's safe to say he took at least 1-2 points nationally away from Carter, though probably not more than that. Many voters who vote third party would probably stay home entirely in a 2 way race.

And BTW, in 1992, Perot got 18 percent of the votes of liberals and 18 percent of the votes of conservatives. For those who argue Perot cost Bush the election and all that nonsense.
