I've given the cup measurements as an approximate in case it's helpful for you, but you'll get the best results measuring the tomato sauce and flour with a scale. The ratio of flour to tomato sauce is super important for getting the dough to the right texture. A kitchen scale is worth it, I promise. I don't test my recipes with volume measurements. I test them using a kitchen scale to weigh the ingredients. I used an online ingredient converter to figure out how many cups of flour and tomato sauce that would be but I can't guarantee how accurate it is. Depending on how you scoop your flour you might end up with more or less than I did! And depending on what brand of measuring cups you use, you might end up with more or less tomato sauce than I used. If you decide to use cup measurements just know you might need to add more flour (if the dough is too wet) or more tomato sauce (if the dough is dry) to get the dough to the right consistency!
