Ok good. You already got your $1,800. So the $1,800 on line 30 is added for her. It is included in your refund or reduced the tax due. You don't need to amend. You got the total $3,600. You got it all. Your $1,800 is not on line 30, only her $1,800. You already got yours. Line 30 is only for the missing $1,800. Otherwise you would be trying to get yours again.
