What happens if you have filed your taxes and a new 1099-R comes in but there is no change in your refund amount as a result?

I have filed my taxes and I'm due a refund.  Today a new 1099-R I was not expecting came in for a direct rollover to an IRA.  None of the rollover was taxable and thus did not change my refund amount.  What action should I take since my return has already been accepted?
