It is difficult to investigate since the original statement of “$21 million for ‘voter turnout’ in India” doesn’t give any reference to the actual grant.
Some sources suggest that the referenced grant is [0], as this is allegedly the only grant for $21 million by USAID that matches the description. It is for Bangladesh, not India, and the money appears to have gone to various pro-democracy advocacy groups. While I suppose you could argue about whether the US should “spread democracy” around the world, I don’t see that you can say this is fraud rather than merely government spending one disagrees with.
