This must be a bug in the latest update as I got this message as well starting yesterday.
This is an informative message, so it seems like whatever check is being used to see if your company deferred tax withholding is incorrect. While I understand that won't impact filing, it doesn't inspire a lot of confidence that the calculations that do matter are correct.
I switched back to Turbo Tax because H&R had bugs in my state calculations in a previous year, but I guess I'll consider both again next year.
