        <ExplanationTxt>| Explanation:| Im not sure if I have this in the right place but in Part VI or the next part below where it has Business Officer Details its prompting me to put information in there through the Tax990 software. We didnt have to put anything there last year. This Section didnt exist for the Business Officer Details in the Form 990-EZ for 2024. I wound up putting my name and Chapter Position as Treasurer for NTEU Chapter 141 as it asked so that the error would go away in the software. But this is a non-profit and not a Business. I just thought that I would clarify that. If anyone has any guidance on that and could email me with the email address that I provided in that section that would be great as well as to whether or not I have to fill that section out in the future. Thank you Don David Berube.</ExplanationTxt>
