I am not aware of any IRS requirement that a 1099 be provided on any required form, but the IRS website at www.irs.gov has a lot of obscure information and it may be best to do your research from the horse's mouth, so to speak. Hope this perspective helps!
Sounds a little suspicious but if you already verified it with a trusted number from Chase, it sounds like they stand behind the document. I don't think it hurts to submit the form you received unless you are disputing the amount shown or the entity that should be issuing it. Hopefully you can also use Form 982 to get rid of this "Income" and not have to pay tax on it. I wrote a legal guide about the subject:
The dialogue on this website does not constitute legal advice nor does it form any sort of attorney-client relationship.
Is it a corrected 1099C? If it was sent after the 31st of January, this could be the case.
The information on this site is not, nor is it intended to be, legal advice. Attorney Satterwhite invites you to call or e-mail for more information, however, visiting his website or contacting him does not establish an attorney-client relationship. Please do not send information that may be considered privileged or confidential prior to establishing an attorney-client relationship.
