All of the previous posts above predate the introduction of the bug that you experienced, so they have some other cause. I made the statement so that others viewing this question would not necessarily think that deleting and reentering the Form 1099-SA is the fix for any of the previously mentioned cases where an HSA-related amount appears on Form 1040 line 21. For the previously mentioned cases, deleting and reentering the Form 1099-SA would only correct the problem if the user originally entered the Form 1099-SA incorrectly or answered the follow-up questions incorrectly.
