Since the tax years that have been impacted so far are 2021 and 2022, those are the years for which you need to include the Maryland 502INJ. Until any action is taken on tax returns from any other year, do not re-file for any other prior years except 2021 and 2022.
The instructions for Maryland 502INJ say that the form must be included with your tax return instead of being filed on its own. Since nothing on the return has changed except for adding the 502INJ, mail that form attached to copies of your 2021 and 2022 returns.
Also, be sure to include the 502INJ with your state return each year moving forward until the issue has been resolved.
