You can use any name like I Bond interest and put the amount in box 3.
Bond interest goes in box 3, not box 1. You have to check the little box under box 1 that says my form has more boxes for it to open up.
If this was an electronic I bond, you can log in to your TreasuryDirect account and download the Form 1099-INT. TreasuryDirect does not mail these Forms 1099-INT, they only provide them by download.
If this was a paper bond cashed at a bank, the bank is responsible for issuing the Form 1099-INT.
I cashed some in at Wells Fargo. They said I wouldn't get a 1099INT for it but they sent me one in January!
