Scammers or an Error? (Corporation Tax Notice of Penalty Determination Failure Letter)

Hello, I'm the owner of HEL MORT ARTS LIMITED, Company number 13989040. On April 29, 2024, I received a letter from HM Revenue and Customs stating that I must pay a penalty of £100 for failure to deliver a tax return for the period from March 19, 2022, to March 18, 2023. However, as you can see from your website, the next statement date is March 18, 2025, due by April 1, 2025, and the last statement dated March 18, 2024, I paid everything and the company is dormant. Now, I'm not sure if this letter is a mistake made by HMRC, if I made a mistake, or if there are some scammers looking for easy money. How can I check it? Thanks
