Tax amount due increasing when I select that my child is "enrolled in a program that leads to a degree ...."

Why is TT increasing my total tax owed if I select that my child is "Enrolled in a program that leads to a degree, certificate, or credential" in the Student Information Worksheet.  My return already shows I am not eligible for any education credits due to income limits. If I check this box in the Student Information Worksheet as  "Yes", my tax goes up by $1736. That is the only box not filled out on the Student Information Worksheet.  Any thoughts would be appreciated!
