when I am amending my 2021 return to include some interest income that got left out, should the amount I enter be the total corrected amount of interest, or should it be only the difference between the correct amount and what I entered on my original return? It's unclear in the Easy Step menu what I'm supposed to enter, and when I look at the "Forms" view of the 1040X the "Original Return" column is all zeroes. I can't tell if it gets populated automatically somewhere in the process.
