how can I correct form 3800 line 1bb(c) ?

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?
