Where do I enter federal income tax withheld for Form 1099-K?

Software version:

2021 desktop self-employed version

 

Background info:

I got the 1099-K from my merchant service provider for 2021.   In Turbo Tax, under General Income, I put the amount from the 1099-K box 1a.  But then there are no more prompts to input the federal taxes withheld from box 4.

 

Questions:

Where do I enter the federal tax withheld?  Should I just enter my income under the 1099-NEC section instead?

 

I attached screen shots of the Turbo Tax sections I'm talking about.

 

Any help would be greatly appreciated!
