How to Report Technical Error? Software won't allow person to enter more than 50,000 (vs 100K) into amount of an RMD that was transferred directly to charity. Why?

I entered the full amount I took for an RMD from one brokerage. Then software asks how much of the RMD was transferred directly to charity.  Software is supposed to allow an amount up to 100,000.  But, software will not allow person to enter more than 50,,000.  A software flaw??
