Thanks @Carl, the doc and everything you wrote in this thread is super helpful!
As I see it, TurboTax is really quite weak in the way it handles this, because it does not know how to correlate losses to assets. So you end up having to re-enter everything and make them match.
Instead, in the loss section, it should let you just pick a schedule E asset, ask you for loss date and insurance payout, and manage the rest painlessly.
But with the right guidance, the more 'manual' way works, so thanks for that. 😀
