State tax filing

I am having the same problem.  The state abbreviation for California seems to be coded incorrectly, as “C”, not “Ca”.  The drop-down menu for the full state correctly identifies the state of California, but the state abbreviation is incorrect.

 

The error message reads: “Sch OSC(1): State Code is not a valid state for this credit.  You must claim the credit on CA’s nonresident return.”
