Box 3? Box 6?

Box 6 is Fed withholding.

For that notation: "If we show an amount in this legend, either the Treasury Department applied that amount to a debt or debts owed to other Federal agencies; benefits were withheld to pay child support, alimony, or court ordered victim restitution; and/or benefits were withheld to pay debts to the IRS."

You would have to know why they were garnished, to know if it is reportable at all.
