Do I need to amend?

Hi all,

 

So here’s my situation:

I already filed my taxes and received my return from the IRS, and I just now received a new 1099-OID that I was not told was even coming. The amounts are basically all 0 except box 2 which is like 5.56. Should I file an amended return? Or is it okay because the IRS has already approved my return? 

Thanks!
