Hi there - Lindsey here. Not to worry - this is completely normal as this just means we've been able to manually submit your site to Ad Manager and now Google is simply in the process of reviewing your domain. :-)
While this process can take a few days, it can take up to two weeks to complete. Should you not see any updates with this status after two weeks have passed, please let us know and we can investigate this further for you.
If you have any questions or need any clarification regarding this, please let us know and we would be happy to help.
