Turbo Tax has NOT fixed the CCA override / NetFile submission.  Yes, you can override the your CCA claim. However, once you do so attempts to netfile your return fails due to the override. You must mail in your returns ($13.50). 

I override my CCA claim and was able to netfile with no issues, it was fixed with the latest update. 

As of 5 minutes ago, I am still not able to NETFILE with the CCA override.

@jfs0110 In TurboTax Desktop, in Form mode, here how to claim zero (0) CCA without getting an error in the Review.

Thank you for choosing TurboTax.

Setting column 17 to a rate of 0% on my portion of the CCA, would also zero out my CCA. I'm trying to claim only my half of the CCA, not bring it to zero.  But overriding the CCA to anything but zero seems to prevent me from netfiling.

@jfs0110 You can override (F2) and would be able to Netfile.
