Turkey has already chosen to do whatever serves her security without being dictated by the arms supplier. As for being under the influence even the US is under the influence. So the question is who's not under some sort of influence? What kind of influence is the issue here and for Turkey the kind of influence Russia has over Turkey is not harmful for her security and that is the bottom line.
Turkey and Russia have a turbulent past:

During the course of Cold War, Turkey was not on good terms with USSR and NATO offered security. Recep Erdoğan is a power hungry tinpot dictator in the making; he is untrustworthy, unpredictable and reckless in his decision-making.
It is an open secret that Erdoğan and Fethullah
Gulen were close to each other and both were of the view that Turkish military should be detached from Turkish politics. However, the two drifted apart over political disputes and Gulen moved to the US in 1999. Now Erdoğan wants the US to extradite Gulen to Turkey because he pins the blame of 2016 coup attempt on Gulen. US requested solid evidence of Gulen's involvement but Erdoğan failed to provide such. In fact, Erdoğan benefited immensely from 2016 coup attempt and managed to consolidate his power further. Food for thought:

Turkish homegrown political turmoil has spilled outside its borders and turned into a source of friction between the US and Turkey since 2016. Erdoğan is obliging Russia in order to exert pressure on the US to hand over Gulen to him. US have taken a principled stand on this matter that Gulen will be extradited when solid evidence of his involvement in 2016 coup episode will be presented. Russia, of-course, is a beneficiary of this friction.
Reality is that Erdoğan is a
manchild; he thinks and acts like a
Sultan, and wants to be obeyed without question. He have his share of supporters but there are many who despise him. Turkish members of this forum do not represent the prevalent sentiment in Turkey in regards to Erdoğan; one of my colleagues have visited Turkey several times and he has a lot to say.
Time will tell whether Erdoğan was a blessing for Turkey or a bane.
