Why touch panel dosen't change size?

Hello, I tried to scale my game with RenderTarget2D, it’s work fine, but when I tried change touch panel size, but when I touch the screen it’s return me unscaled value.
Theres my code
scene = new RenderTarget2D( GraphicsDevice, 480, 800); graphics.SupportedOrientations = DisplayOrientation.Portrait; TouchPanel.EnabledGestures = GestureType.Tap; TouchPanel.DisplayHeight = 800; TouchPanel.DisplayWidth = 480;
RenderTarget draw code took from there
