Hi! @Japple2222 Thank you all for taking the time to post about the Notes in the Community. We have some additional information about them for you:
Prior year notes are currently available within tax years 2024-2019. Comments is the note functionality for new return notes for Tax year 2025 moving forward. The product team is working to make Tax year 2024 notes available read-only within tax year 2025 to help with the transition.
More updates are to come on timeline of release and persistent comments across tax years.
