Inherited IRA

Age 66, retired January 2023 living on savings.  Inherited IRA from mom who passed 12/21.  When do I have to start taking minimum or do I have 10 years to deplete. total amount.  I plan to start social security when I turn 66.6 in March 2023 and have a small pension $800.00/mo that I can access at any time.

Thank you .
