1099 NEC- box 15 is empty, box 17 has an amount, and the state tax ID was blank. The ID later given to me has the wrong 3 letters at the end for my state. What do I do?

The 1099 NEC was issued because I received a stipend from an organization for an internship required to graduate from school. As I stated, the tax ID was initially blank but I was told that if I entered an amount for box 17, the state tax ID was required. I reached out to the organization who provided me with a 14 digit number but then I was told that the 3 letters at the end of their number did not match those for my state. I was given STC but my state is WTH. I am trying to understand if this is an error on the part of the organization or if I am doing something wrong.
