We received 1099-C forms for cancellation of debt. The forms are labeled Tax Year 2013 and the event date is 2013. Are we supposed to include these on our 2016 return?

[DoninGA · Accepted solution]

No.  They are to be reported on your 2013 tax return.  You will need to amend the 2013 tax return that was filed and accepted by the IRS using Form 1040X.
