Do I file a 1040 if I have been in a department of corrections

[shanehays725-gma]

I was told I could get 10% of $30,000 for the last 3 years if so.

This isn't a provision of federal law.  You might check with your state's Department of Corrections to see if such a benefit exists at the state level.

Someone who's been incarcerated generally has the same tax obligations as other people.  See the TurboTax Help article Do I need to file a federal return this year? for filing requirement information.
