Just got this from Intuit...
Hello Todd,
This is Suzie with Intuit's Office of the President. We received your correspondence and I will be your personal advocate while we address your questions. This year, how the IRS is accepting the 1116 Schedule B is through a PDF. At this time, our engineers are working to update TurboTax to be able to e-file the information with PDF capabilities.
The estimated date for the update is March 31st.
