@imoknu Are you using online TurboTax or are you using desktop download software? It is not clear from your post which software you are using, although your reference to clicking "Add a state" suggests you are using online. If you are using online TT, there is a fee for every state return you prepare. The fees are separate in online for federal and state. There is no extra fee to e-file when you use online TT. The fee is the same whether you e-file or file it by mail. If you prepare a state return using online TT, you have to pay for it. Filing it by mail will not make it "free."
If you are using desktop download software, the program will usually include ONE software download for the specific state of your choosing. With that download you can prepare multiple returns for that specific state, but there is a $25 charge to e-file those state returns. You can file them by mail to avoid the state e-file fee. If you need to prepare a return for a different state, each state software download will cost you $45, and then you will also contend with the $25 e-file fee.
