The TurboTax online editions are only for tax year 2020.
TurboTax does not support tax years prior to 2017.
There is no reason for you to file a 2010 or 2011 tax return unless you have taxes owed for those tax years. A tax refund for those tax years will not be sent. Filing for a tax refund had to be done on or before 3 years from the due date of the tax return.
