Tax Year Prior to 2020: I opened a line of business credit $30G for new business. Used portion for training program. No business was made last year. Can I claim as a startup expense? If so, how?

The training program was targeted for that new business. I understand if I was not in the business at that time it was incurred, one could write off as continuing education. Since I was not in the business at that time, can I claim as a startup expense? And where?
