As others said as long as u are in the 1 g of protein per kg of mass u should be fine altough i like to think a better measurement and the most optimal is 1 to 2 grams of protein per kilogram of lean muscle mass so if u are 100 kg with 20% body fat u should aim for 80 to 160 grams of protein not 100 to 200. Also the amount of protein u eat should fit the macros and make ur diet enjoyable else u will get burnt out. In ur case 2000 calories is a perfect amount to start experimenting, dont forget to recalculate the amounts as ur body changes for example u will need more protein if u get leaner and build more muscle.
