I too have Oregon tax returns which rejected over the federal tax subtraction.  Needless to say, clients are unhappy to hear this and now the refunds will go down.   I received the reject which said the software would be updated 2/17/2021, today, and it has not yet.  Am I reading this correctly it will be when?  Isn't there a limit on how many times you can e-file before it must go to a paper return?
