Savings bond interest

I have several US Savings bonds that accrue interest as the years go by. I am not cashing these bonds. I need to know where and how to enter the interest gained each year.  Since they are not being cashed, I do not have a 1099 int, or FEID to enter. In the past my father has entered each year's interest manually on our taxes, but I cannot figure out how to add it using Turbotax.    I was unable to enter the amount for 2023 and am working on 2024. Can anyone assist with where to find the place to enter the interest on uncashed bonds, without a 1099 INT?
