I'm in the same boat. All other states have been accepted. Colorado has been pending for over a week and there is no record of the filing on the Department of Revenue website, although I did get the email telling me my return was sent. I'm assuming this will go through eventually. I imagine they get flooded around both the regular and extended tax deadlines.
If it turns out to be a TurboTax issue and CO slaps me with a failure to file penalty as a result, I will naturally expect Intuit to pay it. But I doubt it will come to that.
