I traveled to Italy for 1 month. The time was divided into 40% volunteer, 30% sightseeing and 30% self employment work. Am I able to deduct the 30% that was work related?

The 30% of self employment work was shooting stock photography and stock video footage to sell. 

If I could deduct any amount of the trip that would be helpful.

I'm using 2018 Turbo Tax Home & Business (Personal & Self-Employed)
