I'm glad this does not appear to have tripped up a lot of people, though I wonder how many it may affected but they did not realize it. In regard to whether the IRS would allow it, note that on the form 8889 Instructions under line 6, it explains that spouses can choose how to split the allocation. For my two cents worth, that fact alone should indicate that Turbo Tax give the user the option to modify the allocations in the Step by Step format.
I do appreciate the time you have given to my question. Could you also respond to the second paragraph in my last message regarding when and how Turbo Tax updates it's data when an amendment is filed for a prior year?
Thank you
