Allowable medical expenses

I am experiencing a problem that came up several times in your forums.  I did NOT enter any medical expenses but a Tax Credit is listed.  I have no idea why and more importantly, I cannot click on the amount to drill down to details of this expense.  There is also no reasonable hints or references to find this information.

 

I would first like to know where this value is coming from.  I cannot submit illegitimate data to CRA.

 

more importantly, as a programmer, I believe the user interface needs to be improved to make the summary information traceable back to the original data.

 

thank you
