I just received a notice from the state of Colorado for one of my clients for a 2017 tax return that the State Income Tax Deduction is incorrect.  I used ProSeries Basic and it didn't use the amount that is listed on her Schedule A line 5.  My client itemized deductions and also had enough itemized deductions without line 5.  Of course, they owe more money.  She was not a high income earner, nothing unusual about her return.  Single mom in her 30's working as a teacher.  Called ProSeries and of course they have no idea and can only help with the past 3 years.  The issue I have is that this is the number that defaulted and I would have had to override the amount and shut off the error check to file it with this amount.  What am I missing?  Is this an error in ProSeries?  Where do I go and who do I turn to?  The return was filed in April of 2018 so plenty of time for updates.  I haven't seen anyone else with this issue, so I am thinking this is something I did?  Help!  Thank you
