You are absolutely correct. I have verified that it does not efile the 8283 if you take the standard deduction in the federal return, even if you itemize in your state return and there is no way to force it to do so. I am also unable to efile my state return due to this issue. If I include form 8283 in my state return, then I am not actually sending what was filed with my federal return. The additional problem is that one is supposed to be able to carry over charitable contributions that are not taken and accumulate them to eventually itemize. To do that, one should file the 8283 in the federal return, even if you take the standard deduction.
I have noticed that no one from turbotax has responded to your thread, nor has anyone responded to my thread with the same issue. This is very poor support not to even acknowledge that there is an issue. That to me suggests that turbotax will not fix this, if ever.
I will be calling them to ask.
