I'm single on social security and part time job. Will itemizing lower my taxes

Probably not.  Your total itemized deductions would have to be greater than the Standard Deduction for your filing status to have any tax benefit.

Standard deductions for 2023

Single - $13,850 add $1,850 if age 65 or older
Married Filing Separately - $13,850 add $1,500 if age 65 or older
Married Filing Jointly - $27,700 add $1,500 for each spouse age 65 or older
Head of Household - $20,800 add $1,850 if age 65 or older

 If you did not have enough itemized deductions to exceed your standard deduction of $13,850 then itemized deductions have no effect on your refund or tax due.     And..you say you had Social Security and a part-time job.  Was any tax withheld from the SS or by the employer for the job?  Is there an amount in box 2 or box 17 of your W-2?
