Get your taxes done using TurboTax

In TurboTax, when I tried to download my state (DC) in early December, it (the TurboTax state download window) said to try back around December 9.  On December 10, I was able to download DC in TurboTax and install it.  It was at that point I started having problems.

 

Checking other Community discussions, this has been a common problem since at least 2019.
