Hello @Tradehome!

Welcome to the Klaviyo Community 

Once you hit done after you send yourself a test, you will get back to the campaign, you will click on the SAVE button on the top right.

You should see the page below… you will then click on Continue to review (circled in green in the bottom right) and it will take you the Review page in which you can then schedule or send the campaign.
 

Please let me know if this is what you were looking for.

Thank you!

Alex :)
