I have a client who is a MO resident and received a large K-1 from an estate in CA.  We are entering in the Federal total and then "State if Different" which should be CA and the State Source Amount but the State Source Amount drop down will not allow anything other than MO for the source.  We have set up the return correctly and all other sections after 1-8 allow for sourcing to CA.  The MO return will not generate a MO CR for tax paid to CA.  I feel like we have tried everything... what am I missing?
