I tried e-filing two with the updates and both were rejected. 

Error Detail:
If Form 11~6, 'ForeignTaxCrCarrybackOrOverAmt' has a non-zero value, then a binary
attachment with description 'Form1116Schedule8' must be attached to 'ForeignTaxCrCarrybackOrOverAmt' and 'ForeignlncmSection951Alnd' must not be
checked. ·

Error Resolution:

"A PDF attachment file is required to file this return electronically. The functionality of
attaching the PDF attachment file "Form1116ScheduleB" is not currently available. The
functionality will be added in the future release. Please check form availability and wait
until Schedule B (Form 1116) is in the product."
