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

[sussygasa]

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.

@Kosetife and @DaveF1006 here recommend this treatment.  Follow these steps:

• Down the left side of the screen, click Federal.
• Down the left side of the screen, click Wages & Income.
• Scroll down to Less Common Income and click on the dropdown menu.
• To the right of Miscellaneous Income, 1099-A, 1099-C, click the Start / Revisit button.
• To the right of Other reportable income, click the Start / Revisit button.
• At the screen Any Other Taxable Income, click Yes.
• At the screen Other Taxable Income, enter a description such as “Colombian Social Security” and the amount.
• Click Continue. 

The entry will be reported:

• on line 8z of Schedule 1 of the Federal 1040 tax return, and 
• on line 8 of the Federal 1040 tax return.

@Leonard provides advice on exchange rates here.

You have a choice of which rate to use, so use the one that is most beneficial to you.  According to the IRS:

Use the exchange rate prevailing when you receive, pay, or accrue the item. If there is more than one exchange rate, use the one that most properly reflects your income. You can generally get exchange rates from banks and U.S. Embassies.

I see no tax treaty listed with Colombia here.
