State tax filing

Going back over my taxes, I've run into the same problem.

Line 22 on IL Schedule M shows dividends from US Government Securities for only 1 of my funds, and that represents only half of the relevant dividends that I received. 

I've looked for a step in which to enter the appropriate number(s), but I cannot find it.

Then, I tried to enter an accurate number directly into the form, but it would not allow a change.

How does this Illinois deduction get entered into TurboTax 2024?

Thank you,

Howard
