Public Safety Officer Early Withdrawal Penalty

I am a retired public safety officer 55 years old with 28 years of service.  I received a deferred retirement payment that I rolled over into a IRA.  It is my understanding that there is a waiver for the 10% early withdrawal penalty.  Is there something my bank has to complete for this waiver or will it come up when I do my tax return at the end of the year?

 

Thanks,
