Using holdout and composite in Photoshop

Hi, I need separate renders that can be composite in Photoshop.
Inside compositor of Blender, it is okay, but once I go to Photoshop, the white fringe or gap occurs.
I can’t composite inside Blender since those images must be uploaded to website separately.

Is there any check box or setting I can use??
