How do I add NC copy of tax return to CA tax return when I efile?

[catherine3]

My clients are CA residents and they have also income in NC. They are getting a credit on the CA return for taxes that they paid in NC so that they are not taxed twice on the same money. I need to add a copy of the NC return to the CA return. How do I do that and Efile? Thank you.
