Pat turkey dry with paper towels and season with salt and pepper.
In a large skillet, heat 1 Tbsp butter over medium-high. In batches, cook turkey until cooked through, about 2 minutes per side. Transfer to a plate and tent loosely with foil.
Reduce heat to medium, then add onion, tomatoes, and remaining 2 Tbsp butter; cook until onion has softened and tomatoes have broken down, 6 minutes. Add paprika and cook 1 minute.
Add broth and cook, stirring, until slightly thickened, 2 minutes. Remove from heat and stir in sour cream. Return turkey to pan along with any accumulated juices. Sprinkle with dill and serve over noodles.
