When is the 1098 form generated and how often ? Never received one !!

According to this link, the IRS requires most of these forms (excluding 1098-C) to be completed and sent to taxpayers by January 31 of each year so that taxpayers can use the information to complete their tax returns. If not received call financial institution, or educational institution, etc., sometimes they do digital delivery too. 

Also check this link which states, if you don't have your 1098 for mortgages:

 "That's OK. You can get your mortgage info by going to your lender’s website. Other documents, like your monthly mortgage bills and your Closing Disclosure (or HUD-1), will also have some of this info.

Your lender should send you a 1098 by January 31. If you haven’t received one by then, contact them for the info you need.

If you don't have your 1098 for education, the institution should have more information, I'd refer you to your school or student loan lender, or school records online and tuition payments, or qualified educational expense receipts.
