I called Lacerte it was clear they have very little info on this.  He did say that they are waiting on the IRS to to revise the 8990 form.  So that part hasn't even been revised. It seems like they threw this out there a little too early.  I think if you have no NOL or excess business interest issues, you might be safe to just check the box and move on.  But hold those returns that do have those issues.  But that's just my guess based on what little information I got from my phone call to Lacerte.
