I doubt, there is such a thing as non-totalitarian Russia in your textbooks. But if typographical error was accidentally made, then, obviously, there were no unemployment those times. Non-totalitarian societies are societies with full employment.

Uhm... could you, please, enlighten us what period of our history (exactly) do you mean by "totalitarian"? Because, you know, Western version of anti-Russian history quite significantly differs from ours. Say, you see Ivan the Formidable (who is labeled "terrible"), Stalin and Putin as "totalitarian tyrants", while most of Russia and neighboring countries don't. Quite on the contrary... but that's another story.

If you're talking about pre-Revolution times (1917) then there was only a so-called "industrial unemployment", i.e. Russia wasn't that industrially developed. Most of the population had lived in villages, and as you probably can guess, farmers ALWAYS have a job in this or that form. Actually, the "job" itself had somehow different meaning back then.

Total unemployment was relatively small, but if we're talking about "industrial unemployment" then it varied depending on the exact year and even month (15-60%).

I doubt there were records in Czarist Russia regarding employment figures (before 1920)

If, by pre-totalitarian you mean Soviet Era, then it was Zero
