I am unable to find information about a person named "Maharana Jeet Singh". It is possible the name is slightly misspelled, or the person is not widely documented.

However, the title "Maharana" is historically associated with the rulers of Mewar, a region in the present-day state of Rajasthan, India.

If the name is indeed related to Mewar's history, the state would be Rajasthan. However, without further information, I cannot confirm that this is the correct individual you are asking about.
