Larry Dean thanks for you clear and thorough explanation. Your input allowed me to finally transmit my federal and state taxes last night. After the last few days I understood that this new form (Form 1116 sch B) would have to be filed as a pdf file attachment. However it was your mapping of each step and setting up the attachment file in the right directory that allowed me to finally transmit successfully. Very disappointing performance and follow-up service by Turbo Tax this year. However contributions and answers on this site allowed me to overcome the problem.
