I've amended my 2024 1040. That changed my state 1040. Should I send both pre and post amended state forms? There was no tax due before but there is tax due after.

You should send your original State Return.  When it has been processed, then submit your Amended state return.

 

You can undo your state amendment to get back to your original return. 

 

Here's more info on Filing Federal and State Returns Separately.

"Mail the amended state return, if you haven't filed your state return yet."

 

Why do you say these things? you canoo file an amended return if you have not filed the original.

 

@lcscherzer123 

If you did not make you own copy you no longer have the original state return becuase TurboTax overwrites it with the amendment.

Never mind. Problem solved.
