There's an income limit to be qualified for this tax break* ($111,800 if single, head of household, or qualifying
surviving spouse; or $175,200 if married filing jointly). The kicker is that the savings bond interest is added to your regular income in determining whether you qualify. Married filing separately is not eligible.
If that's not the case, go back and review you interview answers. It can be tricky. You may have specific interview step questions.
*And a phase out beginning at $96,800 if single, head of household, or qualifying surviving spouse; or
$145,200 if married filing jointly
