Retirement tax questions

I'm trying to enter Box 20 Code Z information into the tax return of an LLC owner of the LLC which submitted the K-1 that (properly) includes Box 20 Z information (and an accompanying Statement A). In TTX Business, on the Box 20 screen there's a box to check if Box 20 contains Code Z. I check that box, click continue, and instead of sending me to a screen to enter Statement A information, TTX kicks me back to the K-1 list. Bug?? How to report??
