How to amend only a Federal Return?

How do I amend only my Federal Return? I made a mistake on my Federal Return and I need to amend, however when I try to amend through TurboTax, it immediately takes me to amend my state return after finishing my federal. I don't need to amend my state return, but there seems to be no way to get through it a file my amended federal return without completing an amended state return.
