Not sure what you mean by your AGI for Social Security. If Social Security was your only income, you are not required to file a tax return unless you have a 1095A for marketplace health insurance. If line 11 of your Form 1040 is blank, then if you want to e-file, you need to enter $1 of interest ---this is a trick allowed by the IRS if you need to file a "0" AGI return.
Or...did you mean something else? Please explain.
