I don't see anything in the IRS instructions for the Social Security benefits worksheet or in any announcements regarding the increase to the educator expense deduction.  I think you found a bug.

Good catch too!  This could potentially affect other Sch 1 adjustments that have a limit that has adjusted, like the HSA deduction.  It doesn't come up a lot, but worth watching.

@IntuitDebH  might be able to help draw this to the attention of those who can fix it?
