After you file

The amended return should not be filed with Head of Household on it.  Stick with filing a joint return.  There is no reason to change the filing status and would actually be a disadvantage; HOH has a lower standard deduction so you pay more tax than if you file jointly.   It sounds like all you needed to do on the amended return was include a 1099R.   Work from the joint return and add the 1099R when you amend---enter the 1099R under the correct spouse's name.  Both names should be on the Form 1040X.
