Do I need a tax form for my federal loans I used to pay for school last year?

If you paid interest over $600 you should have a 1098-E from the lender.  If it was less then you do not need one.

 To enter it without it, you will still go into the 1098-E section and enter the interest just like you would if you had the form.

If you do not have the form, and the interest you paid was more than $600 then check the lenders' website.  Some do not mail them anymore and you have to access them on their site.
