The “Login redirect URI” is a setting on your application in the Okta dashboard. You can find that as well as the Client ID in the settings of your application. The Okta URL will look like <a href="https://XXXXXXXX.okta.com/oauth2/default" rel="nofollow noopener" title="https://XXXXXXXX.okta.com/oauth2/default">https://XXXXXXXX.okta.com/o...</a> which you can find in the API → Authorization Servers tab in Okta.
