How can I file my south Carolina state taxes for 2021?

In December of 2022?

State tax filing

A 2021 return can only be filed by mail now.  E-filing is closed.   If you used online TurboTax to prepare your 2021 federal return you can download the CD/download software to prepare the state return.  Or you could just go on the state's tax site to get the form and prepare it using the forms from the site.
