Taxable Portion of Social Security Retirement Benefits

Hi,

The following IRS web page states that I should add one-half of their social security retirement benefits to my "other income."  Is this "other income" gross income or AGI?  This is the IRS page I'm referring to.
https://www.irs.gov/newsroom/dont-forget-social-security-benefits-may-be-taxable

 

I only earned $15,755 for 2022 and after my standard deduction, the taxable amount is $2,805.18.  So I'm wondering, do I add one-half of my social security benefits to the $15,755 or the $2,805.18?

 

Thanks in advance!
