As I noted in the other thread: "My version is TurboTax Premier desktop/Mac."
So, to be clear, I did nothing at all to Line A (or Box A). I left it exactly the way TurboTax made it. I simply clicked the "Explain" box/button on Line B, which generated an Additional Information Explanation Statement form for Form 2210, where I added the text: "85% Waiver". After that, my eFile worked perfectly. Simple. And no phony numbers.
