Indeed but they were under the spheres of influence of different players at various times in history; more powerful players. Take the Baltics; for different periods they were under the Swedes, Germans, Russians and Poles; all countries which at one time or the other considered the Baltics to be areas of strategic importance. Turkey [non Warsaw Pact of course] was never under the Soviets or the Czars but was considered at various times to be a Russia/Soviet sphere of influence due to the strategic area the country was located in. The former Soviet Central Asian republics are still considered to be in Russia's backyard; in it's sphere of influence.
I would not consider Turkey to ever have been within either the Russian or Soviet sphere of influence. An area of strategic interest to them certainly, given the ability to control access to and from the Black Sea. Given the various wars fought between the Ottoman Empire and the Tsarist Russian Empire prior to WWI, it does seem that a number of the current Eastern European nations were either a part of the Ottoman Empire, or were more within the Ottoman sphere of influence than any Russian sphere prior to the end of WWI. Given the chaos and aftermath of the Russian Empire's performance in WWI, and the following Russian Civil War, it also seems that the Soviets were more concentrating on re-establishing control of areas that had actually been part of the Russian Empire proper (albeit populated by non-Russian majorities) until the Civil War.
