I realized I did not file a Expenses and Scholarships (Form 1098-T) for last year's taxes, is there a way to claim them this year?

Thank you! So I uploaded all into the software and added this.
Now, what do I have to do? Seems I cannot do an amendment online.  
Do I have to mail in my return? Which forms do I need to send, all the return forms?
