You know, I called tech support before I posted my questions.  The rep I spoke to was unaware of this, and spent a bit of time trying figure out what was going on.  I did a search on the Lacerte Support/Community page, but I am apparently not good at search words for this site, because nothing related to this came up.  None of my news updates mentioned that IRS had recently updated 2018 forms for the retroactive tax changes.  I finally found the many conversations about this by scrolling through the posts.  They were on the second and later pages.

Sorry I asked.
