You dropped 3k for a bike and the shop did not adjust your position on it? That is wrong !
Too much weight on hands supporting the body is not correct position and may be wrong for many reasons...too many to try guessing on a thread.
All measurement types are just a starting point. Proper positioning means you on a bike on a trainer for a period of time, you need to be stretched and warmed up as well, while a competent adjuster begins the process of getting your body to be comfortable and efficient.
Good luck but you need to have a talk with your shop.

You've not mentioned your height/weight/bike size, etc. At the very least these are helpful stats to even get the minimum of suggestions on this forum.
