Where do I report Foreign Social Security Benefits (Colombia) as a US Resident?

I'm a Colombian retiree with Colombian Social security benefits residing in the US as US Resident (Green card holder), how do I report my foreign social security benefits on TurboTax?

I saw this topic but I'm not sure if this is correct: https://ttlc.intuit.com/community/taxes/discussion/foreign-social-security/00/2849047

Also there's no answer as to what exchange rate to us.
