Turbotax won't let me override a line of text on Schedule B, Part I - Interest

I use TurboTax Home and Business 2024 desktop version for Windows.

I need to override a line of text on schedule B, i.e. Under Part I - Interest, the line Nominee Distribution. I like to add supplemental information on that line and won't be changing the figures in the amount column. When I go to Forms, Schedule B and right click on the line, the Override is grayed out and TurboTax won't let me override it.

In contrast, TurboTax allows me to do this exact thing in Part II - Ordinary Dividends on Schedule B. When I click on the line Nominee Distribution, I am able to edit the line and append supplemental text.

How do I get TurboTax to allow me to edit the Nominee Distribution line in Part I - Interest section?
