Form 8863 Education Credits line 20 & 21 rolled through with my name and SS# not my son's (all other info correct). Where or how to edit?

At the beginning of the education interview, you probably accidentally selected yourself as the  student. 

You will have to delete the student and start over.

Go through the education section again. Go through the entire education interview until you reach a screen titled "Your Education Expenses Summary".  Verify the correct student name.  If not your son,  Click delete  next to the student's name.

Thanks for responding. Does not solve problem. Tried before and after suggestion. Add Student Key does NOT bring up any students options.

Go back to personal info / dependents and make sure your son qualified as a dependent
