Annuity RMD

I have several accounts that have RMDs.  On one account I did not take an RMD as I I met the annual RMD when I add the totality of my accounts that have RMDs.  Obviously, I didn't receive a 1099 from the account from which I didn't receive any money.  Do I have to report any information about this one account and if I have to report it, for information purposes only, how do I do that?
