unable to add details for US government dividends

In 2023 I used Turbotax Deluxe desktop and was able to add details for an entry by using a right click.  In 2024 Trubotax Premiere I and unable to add details.  Right click does nothing.   I receive US Government dividends from multiple securities, each with a different percentage of the dividend being US Government dividends.  Using the add detail, I could account for each of the securities and percentage.  Now I have to do the math outside Trubotax in a different file.  Without the add details capability, I cannot see, in Turbotax, how the number entered was derived.
