I know what I typed are keywords, but that umbrella term would also contain things like if, new or using. Can I just call class, interface etc. types? I feel like that would be confusing because the keyword class is being used for declaring types.

I just found out, the Microsoft documentation calls them "categories of types" here:

Interfaces, classes, structs, and enums are all varieties of types in .NET.

Generally, words that are used by the language are called keywords. This would include class, interface, if, new and many others.

There isn't a term that collectively refers to the keywords that represent types (class, interface, but not if, for). I might call these "type declaration keywords".
