In a medium mixing bowl, combine the cream cheese, sour cream, sun-dried tomatoes, bell pepper, scallions, and basil. Season with sea salt and black pepper, then mix until smooth and well combined.
Divide the cream cheese mixture evenly between the two tortillas. Using an offset spatula or the back of a spoon, spread the mixture in an even layer over each tortilla, leaving a small border around the edges.
Layer the turkey slices evenly over the cream cheese mixture, slightly overlapping as needed.
Starting from one edge, roll each tortilla tightly into a log, keeping the roll snug as you go.
Wrap each rolled tortilla in parchment paper or plastic wrap and refrigerate for at least 30 minutes, or up to 24 hours for make-ahead prep.
When ready to serve, unwrap and slice into pinwheels using a sharp knife. Serve immediately, or arrange in a single layer in a storage container for transport or picnics.
