According to General Vasili Chuikov in "The Battle For Stalingrad," Khruschev was the political commisar overseeing the generals for the critical Volga region. When Chuikov was appointed to the command at Stalingrad, Khruschev asked him, "How do you see your task?" Chuikov replied, "We cannot retreat across the Volga. We will defend the city or die in the attempt." Khruschev told him that was the correct answer and confirmed his appointment. Basically Khruschev was a senior Communist Party member making sure that the generals were on a sound political footing.
During the battle, Khruschev called Chuikov several times to "check up" on him, see how he was doing, and ask what was needed most (answer: ammunition, even more than food or vodka.) Contrary to the movie, Khruschev was not directly in charge of military operations, which, by 1942, were left to the experts.

as a Kommissar his main duty would have been enforcing morale and adherence to proper party doctrine. IOW he was a political officer, not too dissimilar (except he would have authority to shoot people for not being properly enthusiastic) to a chaplain in the US army.
As a KGB officer, he would also be involved (as you mention) in interrogation of POWs and "dissident elements" (iow, Soviets found to be improperly patriotic or suspected of other "crimes" like retreating in the face of enemy fire).
Not the kind of person you would want to make an enemy of, and precisely the kind of person a propagandist would want to see closely associated with a young, good looking, highly patriotic, and very successful soldier who is soon to be elevated to the status of national hero in a time that the country needs national heroes to keep its collective morale up in a war that isn't going exactly as planned.
Saying that he was tasked with planning the city's defense is probably technically correct, but in reality that task would be squarely on the head of Yeryomenko, Khruschev being his link to the Party and ensuring that the operation was executed according to proper Party doctrine and with the right amount of communist zeal.
The movie is based on a book, the book is is a fictional account of the events in Stalingrad written in large part as political propaganda for the USSR. IMDb probably doesn't care about the book being fiction so much as about how accurately the movie reflects the book, which is proper.

Official position of Khrushchev was called the Member of the Military Council of the Stalingrad front (commander A. Eremenko (Yeremenko, Jeremenko)). The Stalingrad front was defending Stalingrad, and later took part in the offensive. This positon is somewhat similar to "comissar" but has nothing to do with NKVD/KGB. He was attached to the front as the member of the Central Committee of CPSU. Comissars were representing the Communist party, not the KGB.
