Did Not E-File State but Filing Instructions Say I Did

I e-filed my Federal Return and want to mail in my Colorado return.  I printed out the return papers and the state return instructions state that I shouldn't mail my state return because it's been e-filed.     I had clicked on the radial button "Do not e-file my state return now, I'll do it later" when filing my Federal.  Has my state been e-filed?  How can I verify so I do not dupicate by sending in a paper copy?  ( This is via TurboTax Premier).
