Tennessee no longer requires a state income tax since the Hall Tax was repealed according to this source from the TN Dept of Revenue.
Ignore the email sent by Turbo Tax since it states in the source "Hall Income tax was repealed for tax periods that begin on January 1, 2021, or later. Please do not file a return for any tax year that begins on or after January 1, 2021".
Since they said please, I would honor their requests.
