Another income tax question

<p>I'm not sure how many of you have done this, but here's my situation:</p>

<p>I cashed some bonds to pay off a loan. The guy at the bank told me that I can declare them for educational purposes so I don't get charged tax or something on them. This is all cool, but how should I go about declaring this? Should I send a copy of the loan statement or something? Or should I request a reciept from the loan company?</p>
