Can't figure out how to get Game Center assets into review

Problem:

Unable to Submit for Review

  • Your app’s first achievement must be submitted with a Game Center-enabled app version.
  • Your app’s first leaderboard must be submitted with a Game Center-enabled app version.
  • To submit your items for review, add an app version for the selected platform.

What I've done

  1. Created TestFlight builds
  2. Created release builds
  3. Run the game through to completion and triggered all achievements/leaderboards with those builds.
  4. Set up Game Center with proper app version information for all platforms.

Do I have to submit it for a release review while I'm still trying to develop the GameKit parts?
