Column A should have had the amounts on the original 1040 that you filed ... if they are not you did not complete the 1040X properly ... so you can try again if needed ( only needed if there were uncovered sales). However you will need to also remove what you added in addition to undoing the amendment (see directions below). Then once the return is backed to how it was filed you can then start the amendment process again ... that way the column A will be populated.
