RMD related to pension payments on 1099-R

I receive monthly pension payments from 3 employer sponsored plans.  Two of those plans show 7 in box 7 and I have no issues in TurboTax.  However, one plan shows 2 in that box because I began distributions at age 59.  I contacted the trustee, and they said they can't change that even though I'm 76 now.

Evidently that one difference is creating my problem in TurboTax.  As in prior years I put down the entire amount as my RMD but I get an error message that says there is no RMD.  I know that is incorrect, so I override that and get questions concerning "correction period".  What am I supposed to do?
