Where to enter performing artist clothing business expenses in TurboTax Desktop Home & Business 2023

My son is a self-employed presenter, who works in the online gaming industry. He sometimes purchases special clothing for use in certain events, usually out-there clothes, brightly coloured, weird, or whatever, that he would not were in his daily life - presenting himself in a certain way, depending on the audience or event.  From research, from what I understand, that clothing can be expensed as part of his business. 

 

I'm using EasyStep method in TurboTax Home & Business 2023 (desktop edition),  and I've not been able to find anywhere to enter the costs of that clothing.  Can anyone provide some guidance please?

 

Thanks in advance,

PJ.
