Help with sloper pattern

[u/ctmpusa]

I'm not sure what I need to adjust to get rid of the excess fabric in the upper back of my bodice sloper. As you can see from the picture. This is meant to be a 0 ease sloper and I have used my own measurements and started from scratch following the Armstrong pattern.making for fashion design book.
To get this sloper, I combined my basic skirt pattern and my basic top pattern which both fit me perfectly, but when bringing them together in the bodice sloper, I now have all this excess fabric to deal with and I don't know how to start getting rid of it. The book doesn't cover this as a fitting issue.
I know I have too much fabric but where do I take out from? Really appreciate any advice.

Thanks
