Which schedule and line should I enter for reporting other income type of foreign financial assets on Form 8939?

I have foreign endowment insurance income. I followed the procedure to enter "Other Reportable Income" for this income, as shown below. Then, when I come to the section reporting my foreign accounts. I need to file Form 8938. I selected "Other Income" and enter the account for "Amounts Attributable to Foreign Financial Accounts". Then, it asked me to enter the "Schedule and Line" for this "Other Income". The example showed by TurboTax is "Form 1040, Line 21". However, I checked another post (https://ttlc.intuit.com/community/taxes/discussion/how-do-i-report-foreign-life-insurance-policy-sur...), it says that it should be "Schedule 1, Line 8".

So, my questions are:
1. Should I choose "Other Income" for this type of insurance income when reporting my foreign financial account?

2. If yes, then, which schedule and line should I enter, "Form 1040, Line 21" or "Schedule 1, Line 8"?

Thank you very much.
