Same here. It's exactly 15% of my US Social Security. But that line also means /add other deductions like the 15% can be put there also. Line 25700 on the T1 is for Other Deductions which this Turbo line is. Upon checking my pdf copy of the T1 return it shows that the 15% Soc Deduction is placed in the correct line (25700) on it. The problem is that Turb labelling shows "Northern Residence/add ded" but doesn't state what the other deductions are that fit in there, like the Soc Sec 15%. The Soc Sec 15% is put there by the program automatically and the typical user is unaware that it was done. Turbo can fix it by redoing the labelling of it in some way.
