I followed the steps you mentioned by deleting my W2 (have a paper copy), clicking on Forms to delete those you mentioned. I was not able to delete Form 5329-T and Form 8889-T; both were labeled as (Not Done) with a red exclamation mark - every time I choose to delete them, they disappear for a second and then come back. I got surprised when I switched back to the step by step to re-enter my W2 and when I saw my W2 is back (and not deleted). I even closed my Turbo Tax and restarted my computer.
