Charlesmhorton: You received a 2014 1099-R, but never received the distribution check, correct? You will definitely not have to pay taxes twice on the same amount.
I would think that the administrator of your account will re-issue your check with the same date on it that the original contained (or at least a 2014 date). Even though you are receiving it during 2015, I would expect that your 2014 1099-R will still be the document you need to report this income. It would get very complicated (due to the RMD rules) to change a 1099-R, etc. because a check was lost in the mail.
But your best bet is to contact the administrator again to see how this will be handled on their end. The simplest way would be for them to just issue you a replacement check with the same date on it. Then you can complete your taxes just like you always would.
Please post back if you have further questions.
