Forget about a waiver, you are not getting one. Serve out your ban, and then hope they overlook your past transgression when you apply for the visa. Going forward your chances of ever entering the USA on a non-immigrant visa are slim even after your ban is over.
Regarding the waiver, there is no form for this process. You would apply for a non-immigrant visa, and if denied solely due to a ban (and not due to immigrant intent), the visa officer may or may not recommend you for a non-immigrant waiver, which is adjudicated through the visa officer and consulate. In your case you did apply and clearly the visa officer did not feel like recommending you, so your case is dead.
Waiver of the Three- and Ten-Year Time Bars
A waiver is available to people who can demonstrate that if they are
not granted the requested immigration benefit, such as a green card,
their U.S. citizen or lawful permanent resident spouse or parents
would suffer extreme hardship.
But extreme hardship is notoriously difficult to prove. It means
demonstrating more than the hardship that any family member would feel
upon facing separation due to denial of a visa. You’d want to be able
to show severe financial, emotional, or medical consequences to one of
your U.S. family members.
