The dua is from Hisnul Muslim, the fortress of the Muslim, in the morning and evening sector, then remembersnce in the morning and evening on the app on my phone which is a part of Muslim Pro, the book is a collection of authentic dua and azkhar. So yes, count it as authentic. And Allah knows best
رب أوزعني أن أشكر نعمتك التي أنعمت علي وعلى والدي وأن أعمل صالحا ترضاه وأدخلني برحمتك في عبادك الصالحين
"My Lord, enable me to be grateful for Your favor which You have bestowed upon me and upon my parents and to do righteousness of which You approve. And admit me by Your mercy into [the ranks of] Your righteous servants."
— Quran 27:19
