Turbotax Business, trust return, California 541, truncates name of trust to 33 characters

I would like to type the name of the trust, in the top box on the 541 return as:

THE SMITH TRUST UA 6/15/95 SUB-TRUST A

But on the California 541, it truncates it to this:

THE SMITH TRUST UA 6/15/95 SUB-TR

There is room left on the line for more characters, it's just arbitrarily cutoff.  This is clearly a bug in Turbotax.  I downloaded the pdf of CA 541 form, and it allows 56 characters for the trust name.

How does a Turbotax customer report a bug to Turbotax programmers so they can fix it ?
