Education

You can claim the interest deduction, if you meet the three requirements:

1. You paid the interest
2. You are legally obligated to pay it (co-signing counts)
3. The student was your dependent, at the time the loan was used to pay for qualified educational expenses (the TT pop up says “when you took out the loan”)

There shouldn't be any reference to you as the student. Try deleting the 1098-E and re-entering it.  Otherwise ignore it. 

Your son can only claim it if:

1. He paid the interest
2. He is legally obligated to pay it
3. He was the student the loan was for
