re: So the tax lady messed up my return....What should I do?

I started college in the summer of 05', finished this past summer 11'

I started filing taxes on my own 2 years ago. This is my 3rd year filing on my own.

I used the credit last year, and the year before last, and im trying to use it this year. Before that, my parents used my school info on their taxes.

Big possibility that my parents used the credit on theirs few years back?

Can you use it if the gov paid your school?
