According to the NTV broadcaster, the examination was not held on Tuesday because Saudi members of the joint working group on investigation into the incident could not take part in the investigative activities.
But it was delayed because no Saudi official was present for the joint investigation, the Turkish official added.
The Turkish delegation, including police and prosecutors, searched the Saudi consulate on Monday after Riyadh gave the green-light.
Trump told reporters on Monday that the denial from King Salman that his government had any role to play in Khashoggi's disappearance was 'very strong'.
Members of the US Congress, including some of Trump's fellow Republicans, are among the loudest voices in the United States demanding answers and action on Khashoggi, who moved to Washington past year fearing retribution for his criticism of the crown prince. Turkish officials have not said if any significant evidence was found. CCTV footage showed vehicles moving from the consulate building to the nearby Saudi consul general's residence on October 2.
Khashoggi, 59, had been living in the US for a year in self-imposed exile and writing columns for the opinion section of the Post.
Trump's warning drew an angry response Sunday from Saudi Arabia and its state-linked media, including a suggestion that Riyadh could wield its oil production as a weapon. The king greeted Pompeo by saying: "I hope you are comfortable here".
He has told the media that Riyadh was being treated as "guilty until proven innocent", adding that Saudi Crown Prince Mohammed Bin Salman has denied any knowledge of Khashoggi's fate.

Saudi Consul General in Istanbul Mohammad Otaibi has left Turkey for Riyadh amid the growing scandal around the disappearance of Khashoggi. Turkey fears Khashoggi was killed and dismembered at the consulate.
In contrast to the president's cautious words, Graham offered a fiery critic of Saudi Arabia. The source said Saudi Arabia must make "a genuine contribution" to the investigation of Khashoggi's disappearance in Istanbul. They put the president at odds with other key allies and with some leaders in his Republican Party who have condemned the Saudi leadership for what they say is an obvious role in the case.
Secretary of State Mike Pompeo met with Saudi King Salman and the crown prince in Riyadh on Tuesday to discuss the disappearance and alleged murder of Khashoggi.
He hasn't been seen since entering that country's consulate in Istanbul two weeks ago, and multiple leaks to USA media, based on Turkish intelligence, say he was killed by a Saudi hit squad and likely dismembered with a bone saw.
Saudi officials have called Turkish allegations that a team of 15 Saudi agents killed Khashoggi "baseless", but US media reports suggested that the kingdom may acknowledge the writer was killed at the consulate, perhaps as part of a botched interrogation. Saudi officials previously have called the allegations "baseless", but reports in US media on Tuesday suggested the kingdom may acknowledge the writer was killed there.
