How to get Foreign Source Income from VXUS Vanguard?

Hi there, I have foreign tax paid from VXUS (VNGRD TOTAL INTL STK ETF) of Vanguard.

While entering the information for Foreign Tax paid section in TurboTax, I am asked for "Foreign Source Income". There was a page in my last year (2020) tax form with title "2020 Foreign Tax paid" with a column "Foreign Income" from which I had got the Foreign source income. But I can't find that page in my 2021 Vanguard tax form. I see the following. Please advise how to compute Foreign Source income from this info or how to find it. Thank you!

Thanks again!
