Does Turbo Tax automatically enter the age tax credit into line 30100? If not, how do I do it?

Yes, it does enter the amount automatically, if you are eligible for it.

How is age amount calculated and what worksheet is it on. It is not on Worksheet for Return as it states in the T1 form.  A number just  added to line 30100 but I want to know how it is and where it can be calculated
