After you file

Thanks for input, but I have offload TT and re-stalled it again, however seems TT remembered your HDD that it still think I'm activating Deluxe, without asking to enter new Premier code at all. 

And I don't think Deluxe has everything that Premier has, otherwise all people will simply just pay for Deluxe and then get Premier version stuff done, then how can Intuit still make $ from Premier? But I sincerely wish you are right, so that in the worst case, I don't need to do any change on my current Deluxe version.
