State tax filing

Many thanks for figuring out where TT came up with the $280 figure.

However, TurboTax is not allowing me to amend the state return. If I choose "amend return", and then check the boxes for both the federal and state returns (in response to "what return do you want to amend?"), it will allow me to revisit all the info I entered on the federal side, but it is not giving me access to the state return to make any changes. 

Any suggestion on how I can amend the state return and make the change you suggested (removing the $750,000 from the value of the IRA)?

Thank you!
