It probably ties back to New York's higher standard for identity protection if there were otherwise no concerns when reviewing the contents of the state return.
If you are not using TurboTax Online, then there will not be a Tax Tools section to access to delete Form IT-201-X.
For TurboTax CD/Download, go to Forms mode. There will be a left menu with a title Forms in My Return. Select Open Forms and in the search box, enter IT-201-X and select Open Form in the lower right corner of the pop-up window.
When this opens, look for Delete Form in the lower left corner.
The good news is New York did not get the state return yet because it has not been mailed in; the bad news is Form IT-201-X should not be generated or included and must be deleted.
