@liztan911 We cannot see from your post what software you are using. As explained earlier--if you are using desktop software there is a fee to E-FILE a state return, even though you got the software to prepare the state return as part of the software package.
Are you saying you are being charged $19.99 for an online state return? That does not sound correct--it would now be an extra $50 to prepare and file a state return using online TurboTax, because the early bird discounts are over. Where are you seeing $19.99?
How can I see my TurboTax fees?
