EDIT: Disregard the below, that doesn't work. That only updates the smart worksheet which isn't part of the e-file. In summary, I don't see a way to e-file the required statement with TT.
I may have figured this out.
In the form view, highlighting 20b and hitting Edit > Add Supporting Details or clicking "+" next to the line opens a window where supporting details can be added. Is this the right way to do it?
