There are two different costs associated with state returns using TurboTax.
First, there is the cost to download each state return. This is ~$55 per state as far as I know but some states may have a different cost. Some TT versions include one state with your purchase cost. If your version does not include a state or you need more than one state, as I do, then you have to pay that the $55 cost for each state downloaded. This lets you transfer information from your federal return to the state return and then do all the state specific things to create a return for that state. You can use a downloaded state return for multiple filers without paying again for each additional filer in that state.
The second cost is to e-file your state return. This is charged for each e-file for each state. Even though you paid to download a state file, that only lets you create a return. It does not allow you to e-file it, that is an additional cost. Depending on your state you may be able to print your return and file it for free or copy the information from TT into a state provided web site to file on-line for free.
For example, I have two corporations. Both corporations do business in Massachusetts and one also did business in New Jersey. I had to pay $55 to download the MA forms and $55 for the NJ forms. I was able to complete the MA return for both corporations without an additional payment.
BUT, if I wanted to e-file the MA returns for both corporations I would have had to pay again for each corporation to e-file. That would have been three e-file fees, two to MA and one to NJ. I chose to print and mail them for free to MA. NJ requires e-filing so I had no choice for that return.
Hope this clarifies the way TT charges. This information is valid for last year's returns as I have not filed my 2020 returns yet but I expect that it still works this way
