Tax is not withheld from your SS benefits unless you requested that. When you enter your SSA1099 the full amount of your benefits shows up on line 6a of your Form 1040, and the amount that is taxable shows up on line 6b.

If Social Security is your ONLY income, you are not required to file a tax return unless you have a 1095A for marketplace health insurance. If you have other kinds of income in addition to the Social Security, then your SS might be taxable.
TAX ON SOCIAL SECURITY
Up to 85% of your Social Security benefits can be taxable on your federal tax return. There is no age limit for having to pay taxes on Social Security benefits if you have other sources of income along with the SS benefits. When you have other income such as earnings from continuing to work, investment income, pensions, etc. up to 85% of your SS can be taxable.
What confuses people about this is that before you reach full retirement age, if you continue working while drawing SS, your benefits can be reduced if you earn over a certain limit. (For 2021 it was $18,960. For 2022 it was $19,560 — for 2023 $21,240) For 2024, $22,320. For 2025 it will be $23,400
After full retirement age, no matter how much you continue to earn, your benefits are not reduced by your earnings; your employer will still have to withhold for Social Security and Medicare. If you work as an independent contractor then you will pay self-employment tax for Social Security and Medicare.
To see how much of your Social Security was taxable, look at lines 6a and 6b of your 2024 Form 1040
