Saudi Arabia denies that bin Salman ordered the killing, despite USA intelligence agencies concluding the opposite.
President Erdogan also said Prince Mohammed had sent his chief prosecutor to Turkey to investigate the Khashoggi matter, but the prosecutor failed to share information with Turkey.
But the intelligence agency has "medium-to-high" confidence that Prince Mohammed "personally targeted" the journalists and "probably ordered his death".
Khashoggi's killing has put mounting pressure on Riyadh and MBS, who Turkish officials - and reportedly the Central Intelligence Agency - have concluded was behind Khashoggi's death.

The two world leaders met for a dinner meeting to discuss trade at the sidelines of the Group of 20 leaders' summit. Trump said Bush's death put a "damper" on what he described as a "very important meeting" with Xi.
The Crown Prince also told associates in August previous year that if he failed to persuade Khashoggi to return to Saudi Arabia, "we could possibly lure him outside Saudi Arabia and make arrangements" - a communication the Central Intelligence Agency said "seems to foreshadow the Saudi operation launched against Khashoggi".
Riyadh initially said that Khashoggi had died in a scuffle at the consulate, however, later claimed that the writer had been murdered in a rogue operation.
On October 2, Khashoggi was reported missing after he stepped into Saudi Arabia's consulate in Istanbul to collect paperwork that would allow him to get married to his Turkish fiancée Hatice Cengiz, who later said that he never appeared from the building. "We do not have a smoking gun [showing] that the crown prince was involved".
Khashoggi was a Saudi national resident in the United States who wrote for the Washington Post.
They also have a record of the prince talking about "making arrangements" to deal with Khashoggi from 2017.

Khashoggi, a United States resident, was murdered in the Saudi consulate in Istanbul in October.
In more than 400 messages sent to an exiled Saudi activist in Canada, revealed by CNN, Khashoggi paints the Prince as someone who relentlessly preys on his critics, saying, "The more victims he eats, the more he wants".
He said solving the killing would be in the Saudi royal family's interests.
"Maybe he did or maybe he didn't!" But some members of Congress have called for further action, and Republicans have begun defecting from the administration over its support for the Saudis.
Pompeo, who met in Buenos Aires with his Saudi counterpart, has backed the war as a way to counter Iran, which has ties to Yemen's Huthi rebels.
