What if i dont have the 1099 form but I know I cashed savings bond

[MargaretL]

Please report the interest AS IF you received the form 1099-INT - if the bank where you cashed the bonds does not issue the form 1099-INT. Use the bank name as the payer and enter the interest in box 3; no additional reporting is needed. 

1. Federal Taxes
2. Wages & Income
3. Interest & Dividends, select Interest on 1099-INT - be sure to check the box My form has info in more than just box 1
