The correct answer is Adobe Stock doesn't accept PSD Templates from regular contributors. They source their templates from trusted designers & partners by invitation only.

"At the moment, Stock is sourcing design templates from a small group of artists and agencies — we’re not accepting submissions from individual contributors at this time."
Regular contributors may submit photographs, vector graphics, videos, 2D & 3D artwork, and Generative Artificial Intelligence images that meet Stock submission requirements. Keep in mind that Adobe Stock customers expect the highest visual and technical quality for use in commercial projects. For more details, read the Stock Contributor User Guide carefully.
