Hello,
There’s an update on the TurboTax help article you’re following: "Why am I not able to e-file my state return after filing my Federal return?".
This issue is scheduled to be resolved in a product update March 19, 2021.
If you’re still having trouble or there’s anything else we can help you with, feel free to give us a call.
Thanks for your patience,
