Unfortunately, that previous thread that you referenced did not directly address my question, or if it somehow did, it was way too complicated. But in the middle of the night, I figured out what to do. I'm using Deluxe and there is an ability to switch to Forms View (as opposed to the step-by-step input view). So I just switched to Forms View and typed in the correct information in column A of Form 1040-X. Column B automatically recalculated. Voila. Problem solved.
