Hi Mathisenrob,
If your problem was the same as mine (cannot eFile) - then you need to review the following section of your State Return.
Follow these clicks within Turbo Tax and check to make sure you didn't accidentally click the boxes that require an ECN.
State Taxes -> Continue -> Edit -> Credits and Taxes -> Health Insurance Penalty -> Revisit
In my case, my return was complete and when I attempted to transmit the return, Turbo Tax stopped me and said something to effect of "We have to ask you one more thing...." and it took me back to the 3853 "No ECN" problem and acted like I MUST enter an ECN even though I chose the "No ECN" option from the drop-down.
The reason Turbo Tax was doing this, was because I had checked a box in during the "Health Insurance Penalty Q&A" that resulted in the choice "No ECN" being problematic. I had to remove the check from the box with the following title: "Coverage was considered unaffordable" which was in the 2nd group on this screen and it was the cause of the failure on attempt to eFile. I removed that check and let Turbo Tax perform the calculation again and my penalty was waived.
Best of luck!
