The pro-Kremlin Channel One station reported that intelligence officers arrested two men over the alleged plot earlier this month.
It broadcast video of one suspect, naming him as Russian national Adam Osmaev.
He and the other suspect, Kazakh citizen Ilya Pyanzin, were said to have been arrested in a raid on an apartment in the Ukrainian port city of Odessa.
Osmaev confessed on camera to being part of the plot.
Channel One said both men were working for Chechen separatist warlord Doku Umarov.
It said they planned to bomb Putin’s motorcade after the March 4 presidential election that the Russian premier is favourite to win.
State media have previously carried reports of assassination plots on Putin close to election time.
