If i have a runner at first, the pitcher attempts to pick him off and overthrows the first baseman do i just click the runner, move him to second and record an error for the pitcher, or is there a more specific way to record the overthrow?

Thanks

That is all that needs to be done.

You can add notes (ie overthrow at first) if you want but statistically it does not matter. Notes make it more fun for anyone following along on iscorecast.
