[1] Where do you see the term "household AGI" in relation to the exclusion of unemployment income? It's not in the information on the IRS web site, or in the law that was passed. They just say "modified adjusted gross income," which clearly means the AGI on the tax return of the person claiming the exclusion.
[2] You can't change the payment date, but it doesn't matter. They have to pay the amount shown on the tax returns that they already filed, no matter when they pay it. If it turns out that they don't owe that much, they'll get a refund by whatever process the IRS comes up with for dealing with returns that were already filed.
