% of US government interest calculation from 1099-DIV

How can I calculate the % of US government interest on an investment dividend?

I know for example that for "fidelity GOVT MMKT" it was 55.08% in 2024.

 

What do I apply this % to?

 

I have these columns in the detailed tax report from the brokerage:

- ordinary dividends

- qualified dividends

- federal income tax withheld

- section 199A dividends

- foreign tax paid

-capital gain distributions

-foreign source income

- qualified foreign source income

 

thanks!
