How do I fix the social security number on an efiled and accepted ta return?

We filed my daughters return with her twin sisters social security number. It was accepted and now I'm pretty sure that I cannot file my other daughters taxes and I"m not quite sure how to fill out the 1040X

Here is one solution I can think of:

Amend the filed return using the other daughter's income forms (the forms that have the same SSN as the filed return);
File the second return (the SSN you have not filed yet) using the income forms you already used (the tax forms you already used to report on the filed return).

Explain on the 1040-X form why you are amending.
