Importing different size psd into AE 2D animation

[D A V A]

I need to resize psd files to match another psd file in 2D animation, when imported, file comes in slightly larger and not in the correct place. Original psd was a different size. I resized in AE to 1080x1920 and scaled down contents using null (not script). When I did this awhile back was just learning, trial & error. How can I now import to match these up expediently in AE? Or  is there a any way to copy and paste bounding box sizes in AE without changing proportion of file contents?

Thanks in advance for any and all help.
