The Schedule B is available by clicking on Forms, then again on Forms on the top menu, and then opening a form. Navigate to the Form 1116, open that, and add the Schedule B to your tax return.
However, there are a couple of bugs in it. For my return I needed to add a value to the 6th past year. Everything seemed to work great, but at the very last minute I got a diagnostic error that said that the value had to be added not only to the Schedule B, but also to the base Form 1116. Apparently these are not connected properly. That was an easy problem to correct, just adding the same amount in both places.
But... when I printed my return to check it... the value I had added to the 6th past year ended up reported by Turbo Tax in the 10th past year. That is a significant bug for which there is no workaround.
I called the support line and got a dude that had no clue about what I was talking about, and was giving me incorrect instructions. I hung up and will try another day to see if I get a smarter support person.
