How much is an additional state in TurboTax Premier 2023

I currently use TurboTax Premier item #314232bfor tax year 2023. It includes a $10 credit for IN-PRODUCT ADD-ONS.

I need to file two state returns.

I already downloaded one free state, but I would like to download another state.

How much will it cost to download a second state?

 

Will there be a problem using the second/additional state since I already downloaded one state which is the state that is my residence? 

I work in a different state and I am having trouble filling in that state by hand because I cannot find questions to my answers. I have to do this state's return first before I can do my home state to get the credits for income taxed twice.

 

Thank you.
