For me, had to declare the default export:

import graphql from 'babel-plugin-relay/macro'
declare module "babel-plugin-relay/macro" {
  export { graphql as default } from "react-relay";

you saved my day!

Didn't work for me when running relay-compiler:

"relay": "yarn run relay-compiler --schema schema.graphql --extensions ts tsx --src ./src/ --watchman false $@"

Parse error: SyntaxError: Only declares and type imports are allowed inside declare module (6:2) in "react-app-env.d.ts"

Ok, solution was to install relay-compiler-language-typescript
yarn add -D relay-compiler-language-typescript
and run relay-compiler like this:
"relay": "yarn run relay-compiler --schema schema.graphql --language typescript --src ./src/ --watchman false $@"
