The short answer
No. One portion of cottage cheese (150 g) gives about 0.2 mg of iron, 1% of the 18 mg a day women aged 19 to 50 need. Its calcium holds back iron from the rest of the meal, so keep it apart from your iron meals.

What holds it back
Calcium
Calcium holds iron back, from plants and from meat.
Hallberg L, et al. (1991), Am J Clin Nutr. 165 mg of calcium from milk or cheese cut iron absorption from a meal by 50–60%, and it lowered heme iron too.

Questions
How much iron is in cottage cheese?
About 0.1 mg per 100 g, so a 150 g portion (150 g) gives about 0.2 mg. The number is from USDA FoodData Central: Cheese, cottage, creamed, large or small curd.
Does cottage cheese block iron absorption?
Its calcium holds iron back, from plants and from meat. The program keeps calcium foods 3 to 4 hours from an iron meal.

Iron is from food tables, for the food as eaten, and real foods vary with the cut, the brand and the recipe. Your body takes in a share of it, and a larger share when your stores are low.
