I already electronically filed a return jointly.  I know I can amend a joint return prior to April 18 and change the filing status to married filing separate.  Filing one 1040X allows me to change the status to MFS just for the taxpayer.  How do I handle the spouse?  I prepared another Form 1040 for the spouse with a filing status of married filing separate and electronically filed but it was rightly rejected by the IRS since the SS# was used on the original return.

Do I merely file a Form 1040 by paper for the spouse with a note explaining a 1040X was filed for the taxpayer or, do I prepare a second 1040x going from joint but this time to filing married filing separate using the spouse's income etc.
