Had similar occur. All was fine and my return was ready to file, now comes a new update and it eliminated the responses to 21a and 21b and said to fix the error I should change the address in 21c to blank. Going through again my 30% credit for hybrid hot water heat pump tank was eliminated. Appears there is a bug in whoever updated this form. Will need to delay filing because of this bug and a potential $2000 error. Please review and repair this update error.
