Preheat oven to 375℉ (190℃) and line a baking sheet with parchment paper or a silicone baking sheet.
Using a stand mixer or electric hand mixer with mixing bowl to mix: cream cheese, heavy cream, sour cream, lemon juice, and 1 ½ tbsp of the powdered sweetener. Mix until combined and creamy. Set aside.
Arrange cheese slices on parchment paper and bake for 5 to 8 minutes, or until the edges of cheese start to brown. Remove from oven and let cool for 1 to 2 minutes (leave the oven on)
Add 2 tsp of the cream cheese mixture to the middle of a corner of each cheese slice and place 2 to 3 pieces of the chopped peach on top. Fold cheese over making a triangle shape and press the outer edge down. It won’t seal but should stay folded (will seal once returned to oven).
Return the baking sheet with turnovers back into the 375℉ (190℃) oven and bake for 2 to 3 minutes more, just to warm the filling in the center and seal the edges. Remove from the oven and let cool for a minute or two or until firm.
Sprinkle the turnovers with the 1 ½ tbsp remaining powdered sweetener and the cinnamon. Serve and enjoy!
