I have overridden my CCA to adjust the CCA that turbotax automatically populates, but my wife and I have shared ownership of the properties. I am claiming my full CCA and my wife is zeroing out her portion of the CCA. She is able to netfile, but I am not. My override shows that I am only using half (my portion) of the available CCA, otherwise turbotax would deduct the full CCA available, which includes the portion of the CCA that my wife didn't use. So, it looks like turbotax only lets you netfile if the CCA is zeroed out with one owner.
