How to check if there is a similar logo?

Question

Design

Hello. Can you please tell me how to check the logo for uniqueness?
Are there any services to search for similar logos?
How do you come up with logos?
After all, it is worth looking into Google, freepik, dribbble and understand that your idea has already been implemented. How to be?
Thank you.

90% solution: www.tineye.com (looking for pictures, the logo among them - already manually)
100% - I don't know, I'm looking for it myself.
