I contacted TT for some help. The only way to input the p'ship paid tax is to go into Forms mode (upper right hand corner on the screen). Then scroll down the forms list to the NC D-400. Click on that. Go down to the box for Line 21c worksheet. Enter the tax and income amount. The tax will appear below that, on line 21c. Go back into Step-by-Step mode.
They obviously need to create an input line for the NC K-1 for this somewhere in the NC state section.
