Yes, it definitely goes to the Schedule C. I might add they are using an old form to report. The correct reporting form now is 1099-NEC.
The name of the business would be your wife's name and the address would be your home address even though she may be going to the travel agency to do the work. There is no separate tax ID aside from her social security number (SSN). An entry is not required for that unless she actually had one. There is no need for one unless your wife was planning to hire employees herself.
The form they report the income on indicates to the IRS your wife is self employed. You use only her personal information, not the company that pays her.
As far as the Business Activity Codes you can use the link to find the most appropriate code for her business.
