Retirement tax questions

PS.  Fanfare, if I stated I was the beneficiary I'm sorry.  I thought I stated that his estate went to probate as he didn't name anyone as his beneficiary.  My family, with permission from probate court, just wanted to setup an IRA for use down the road for my still living brothers and me.  All of the other 1099-R's (5 1099-R) from the other IRA's my deceased brother had, listed my name (court appointed executor) listed as the recipient.
