pension switch to central states

Good morning/afternoon fellow/lady retires;
Was wondering if anyone might know the answer to this. Today I turned 65. My pension is to switch to central states. Got letter from central a couple weeks ago saying I would receive my pension from them starting July 1st 2019. Ok with that I was assuming I had 1 more check coming from UPS but no deposit today. I have been wondering because of my birthday falling on the 1st if it was going to cause a problem with the transfer to central states but trying to get a hold of someone at central because of there office workers strike is something else. Anyone else run into the same situation as maybe or know more about the transfer situation. Thanks
