Here is the reply I got:
My name Erik with Intuit's Office of the President. We received your email and I wanted to provide you with the most current information Intuit TurboTax has about Form 1116 Schedule B – Foreign Tax Carryover Reconciliation Schedule. After further investigation, our Product Specialist was able to confirm that you will be able to E-File with the 1116 schedule B attached as a PDF, once that form is finalized. I apologize for any miscommunication earlier, as it was unclear if this form was going to be able to be E-Filed or not. Form 1116 is final; the schedule B is set for tentatively 3/31. However, our Development Team is working around the clock to try to get the form out ASAP. Again, if you are needing any further information, please contact Technical Support. However, that is the latest update our team would be able to provide at this time.
