I know that Quicken does it. I've been a Quicken user since 1988 (with the DOS version).
Your point is well taken. Turbo Tax could do better based upon the comments in this thread although I do not believe they will ever reach the level of support that ProSystem fx has nor would I expect it to. Fortunately, I've never had to contact them for support.
This is only my second year using Turbo Tax.
