Their amendment instructions (here) say to send the 540 and Schedule X “along with all required schedules and supporting forms,” and this isn’t completely clear to me. But since they’re not specifying that they only want the forms which support the changes, I would send the Schedule CA, with the updated column A interest amount on it. (But according to that schedule’s instructions, foreign interest would not be an adjustment in columns B or C.)
