Yes, you can. TurboTax will compute your self-employment tax and automatically deduct 50% of it for you. You do not need to make any special election for this.
To verify, you can check the total self-employment tax you are liable for on your 1040, Line 23. Multiply this by 50%. Check that the result is on Schedule 1, Part II, Line 15.
In the Desktop version, use the Forms view to see the 1040. If you are using TurboTax Online, print preview your return. If you need steps to preview the 1040, see: Can I print a copy of my return in TurboTax Online before I file it
