My Federal electronic filing is rejected because this line needs to be a zero. The data source for this line is grayed out and does not provide me with the source. However, I believe that the source was probably line 15P from the related K-1. I modified the applicable K-1 to remove that tax credit item, but form 3800 did not change. TurboTax will not allow me to electronically file if I override anything, and yet it is telling me that my federal return was rejected because this line needs to be zero. Is there anything I can do to be able to correct this problem and file electronically?
