My state form was rejected. I tried reentering info to change the error but no luck. Can you change one line entry on the state form?

It is not clear what you mean by changing one line entry on the State Form. However, if you continue to have issues deleting the State return, log out of your Turbotax account, and add the state again.

Below are the steps:

Here's how to Delete and Start over:

1. Sign in to TurboTax and open or continue your return, if you haven't already.
2. Select Tax Tools from the left menu, then delete the State.
3. Answer Yes to confirm.

 How to add a State:

1. Sign in to TurboTax.
2. Now select Add a state (this reopens your return) ...
3. Select State from the left menu.
4. On the Let's get your state taxes done right screen, select 
5. Continue and follow the instructions.
