No do not file another 1040X. You filed the return before the law changed so the computer churned out a notice based on the original tax due amount. They have not recalculated his tax due amount yet even though you sent an amended return---it takes them about six months to process an amended return.
Eventually---sometime during the summer--- the IRS will recalculate the amounts of tax due or refunds for people whose returns were filed before the law changed----but it may take a few more months.
Call the number on the notice you received from the IRS----it will probably be hard to get through---but be tenacious.
