Retirement tax questions

I am a Postal Service retiree, And I had a problem with my Pension RMD, no with my retirement account, The Law was clear, but Pension was something else. Everybody was in the La La La Land. Finally I called the  USOPM and they searched my account and solved the problem. My advice is do not waste time with the branches and go straight to the tree. Patience and GOOD LUCK !
