New Job (independent contractor) as a Restaurant Critic - how to report

I have 2 related questions.

This year, I began a side gig as a restaurant critic.  I am an independent contractor for a restaurant chain, and they pay me to evaluate the food and service in 8 locations.  They have sent me a 1099 for all of the expenses they have reimbursed (each time I review a restaurant, I submit an expense form for the cost of the meal plus any parking costs).

My questions:

1. In turbo tax, do I create a business for reporting purposes?  If so, I cannot find a code resembling what I do, so shall I choose the option with all 9's?
2. How can I indicate that the meal expenses are my job?  In other words, how can I deduct 100% of the meals instead of 50%?  The meals are not simply a business expense....they ARE the business.

Thanks in advance for your help!
