Horizontal Scroll with Anchor to the exact screen

I am trying to have a navigation that leads the user to the exact screen with horizontal scroll, therefore, I re-create the screen with the vertical screen.

however, even though the button leads somewhere near the horizontal screen, but it just simply cannot go to the exact spot which starts from the left side of the screen.

Can someone help me fix this issue?
