I'm having the same issue, except I filed on the 12th after CO opened to receive returns. TT is still showing "pending" for Colorado and the state website shows they've received nothing. I've spent the past two hours trying to get someone on the phone, once I did the call disconnected after I was put on hold for 15 minutes.
More interesting is on the desktop program under File -> Electronic Filing -> Show Electronic Filing History, I'm shown a log after "Your return has been received and will be forwarded to the taxing agency at the appropriate time." is a list of what looks like a repeating error, showing: Colorado Individual: Filing changed state to IN_AGENCY followed by Filing changed state to SUCCEEDED_AGENCY. This grouping of messages repeats another dozen times down the list.
