No one should be trying to answer these questions without knowing the terms of the original trust.  "Joint grantor living trust" tells us nothing.  We can make assumptions that it is a typical revocable trust, but that could lead you down the wrong path.  

The Florida trust is likely a red herring.  What year return are you preparing, anyway?  Was the sale in 2021 and "Florida Woman" is just getting around to sorting out this mess?
