Can I deduct a percentage of my self employment tax?

[pk]

@doriamcmanious , when you tell TurboTax that  you have a 1099-NEC or that  you are self-employed / single member LLC, it will walk you through the process of filling out Schedule-C and then Schedule-SE.  50% of the SE Taxes  would appear as an adjustment  on 1040  ( to make it fair  compared to the wage earners / W-2 ).

Is this what you are asking about ?

The deductible portion (50%) of self-employment tax is deducted on line 15 of Schedule 1 Additional Income and Adjustments to Income.
