Interesting.  ProSeries won't do it without any current year benefits.  I tested it and if I enter $1 in box 10 of the W-2 for the current year, it works.

I also tried entering $1 in box 10 of the W-2, then override line 12 of the 2441 back to $0, and it still seems to work.  So I think that is what I would do.
