FOLLOW-UP:   I got an answer from Intuit.   They told me the IRS & SSA require full SSN for filing.    Yes, I know that.  I've done this for over 30 years.    But I'm talking about the EMPLOYEE's COPY.   It has been allowed & recommended to truncate the SSN to the last 4 digits only for security.  I see these all the time when I'm preparing tax returns.    So I want to be able to do that on the EMPLOYEE's copy of W2s.   The option is there on the screen but is grayed out.  Please activate this option.
