Fees Related to Small Business

Greetings,

 

I have a small business and get 1099-NEC $$

 

When I file taxes I have expenses including Turbo Tax, Audit Protection, etc.

 

Considering my taxes involve both the small business and my personal tax income...

How do I divide up the portion of the expenses above vs the 

personal side of the equation?

My CPA from many years ago said to enter all such expenses @ 100% as a small business expense.

 

TIA,
