Please see this help article for more information to address situations where the second state is downloaded but not showing as installed.
If you are using the web browser to download the second state return, do not open the download from the web browser. Instead, close the browser once the download is complete, then open the file explorer and open the download from the downloads section.
If you are using a TurboTax Desktop product, it comes with one free state (you are only charged for e-filing) and you have to purchase the second state. You can purchase state products for TurboTax Desktop either from within the product or from TurboTax.com.
To purchase an additional state from within the program, open your tax return and select Download State from the Online menu at the top of the screen. If you prepare two state returns, you will generally prepare the nonresident state first. If you owe tax in the nonresident state, you may be able to get a credit for tax paid to another state on your resident state return.
