What is the taxable Social Security amount on Line 6b of your Form 1040?

Up to 85% of Social Security Retirement/Disability/Survivors benefits becomes taxable when all your other income plus 1/2 your social security reaches:

• Married Filing Jointly - $32,000
• Single or Head of Household - $25,000
• Married Filing Separately - 0

If you have zero on 1040 or 1040SR line 6b you may have answered the foreign question wrong or skipped it.  It was on the very next screen after you enter the SSA-1099.
