Can i deduct the cost of getting my teachering certificate and other classes required for me to teach. where would i deduct it on my fed and Nj state

I started to be a teacher in 2018 and I had to get my teaching certificate and there was other courses they had me travel out of state to attend to maintain my teachering position at the school. I had to pay for hotel and transportation. can I deduct these expenses and where on my fed and NJ state tax form?
