Hi, Dear Timo,
you have near zero engagement on your Twitter account, if you check
site:https://twitter.com/timorossa
you see Google indexed your Twitter URL but in ranking it got a low score.
try to make engagement on your Twitter and also people should search more about your name google decided to find a better link version to show in SERP, so you can use your Twitter profile link in other social media: Instagram. facebook,.... to promote it. it will take sometime but these actions will do your job
