According to the below (along with the investopedia link from the other answerer), cashback bonuses from Discover would be considered discounts (not income) because they are contingent upon use of the card. They would therefore not have a reporting requirement.

sign on bonus might be considered income if it is not contingent upon use of the card/account...

Also, if you opt in for paperless statements, or if you have accounts with other banks which only do paperless, you may need to check your online account for the 1099-INT. The bank may (should?) notify you via email when paperless forms are available.
