I'm sorry that didn't work. I tried a few other ways and couldn't find a workaround.

Keep in mind that this is a peer user forum, so Lacerte/Support/Tech team is not reading this.  If you want an enhancement request, post in the "Tax Idea Exchange" section.

Link that post here to this thread in a reply comment.  I'll go upvote it, and I'm sure others will also.  Crowdsource more votes from your peers that use Lacerte.  Make a post in the FB group "Lacerte Rescuers!"

I would also ask your local peers in MA that use Lacerte (maybe your state society of CPAs/EAs) how they handle this.  You can't be the first one experiencing this, and I wouldn't imagine all of them just abandoned Lacerte, or Lacerte would have (likely) fixed this by now.  But also, I realize there's a further subset of MA tax pros who have a client where at least one taxpayer is disabled, and that's probably rather small.

As I'm sure you know with Support, it all depends on the agent you get.  Be very polite, but focused on what you want/need if you decide to try and call again.  "I'm calling to report a glitch in the Massachusetts programming. Can we set up a Glance session so I can demo this for you?" If you can get them to see that there's no way to get a split between page 1 and page 4 on  MA Schedule 1 as far as dependents from Screen 2, you might have success.

Being practical, even if you get a promised fix, this won't happen before 4/15.  Plan to extend these returns.
