Disappointed with Turbotax

After doing my inputs and upon review I saw a $80 Penalty assessed on my state return.  After running through the inputs 2x it wasn't going away.   The line item states if the Balance Due is over $800 then you could be assessed a penalty.  I am getting a refund.  Upon digging into it through the "Forms" I found the problem was;

Since Turbotax has that date in it's information why wouldn't this software use that information and allocate it properly?
