I haven't logged in to 2016 in awhile, but a client is asking for backup from that year to be faxed to her daughter's college scholarship dept.  In addition to asking for my email and password Pro Series Basic is asking me for a security code.  No clue as to what that is, or where I'm supposed to get one. It just has a box for security code and below the box it says please enter a valid security code (and tech support just hung up on me after a 10 minute wait)
