It was updated early. About a week or so ago. If you look at forms.. it will show final. 
I have already done returns in both ProSeries and Basic With form 1116 schedule B with no problem efiling. No rejections. Just make sure you follow the direction of creating the sch B as a .pdf and attach. Drop down will have form 1116 and description will show schedule B…. Yes, schedule B shows up in the list of firms but not eligible to Efile.
