"What kind of stipulation or provisions in the trust should I be looking for."

What you seem to be determining is if the Trust files the info on the house sale, or the daughter, and in either scenario, the 1099-S is incorrect:

"The 1099-S has my clients SSN as the Tax id number on the 1099-s, but the name attached to the 1099 -s is the name of the trust."

And to resolve that, you need to know who owned the property after death. I'd make one of these lawyers straighten it out with the title company, because someone made an error along the way, either in execution or in guidance.
