where are my social security tax and medicare tax withheld reported in 1040

I saw them in my W2, but I cannot find them in my printed-out 1040 after importing the W2....

Those don't go on your tax return.  They are not withholding.  They are a mandatory tax.  You get a Social Security statement each year showing how much income you had and how much credits and benefits you have built up.   You just enter them from the W2 nowhere else.  

The only thing that would show up on  your tax return is if you had more than 1 employer and together they took out too much Social Security in box 4.  For 2023, If you had more than 1 employer and paid more than $9,932.40 in Social Security tax (box 4) combined you get the excess back on your tax return. If you are married it is for each spouse separately.

Generally nowhere except possibly Schedule SE if you have self-employment income or Form 8959 if you are subject to the additional Medicare tax.
