I paid to e-file but did not think it's been filed yet. I forgot to add my 1099-G form and now it's asking for payment again.

The state tax return is an additional charge of $40

There is not charge to e-file a tax return.  The TurboTax account fees are for the use of the software to assist in completing a tax return.  The account fees are the same whether a tax return is e-filed or printed.

Did you do this? -

You complete your tax return by finishing all 3 Steps in the File section. In Step 3, to e-file your tax return, you must click on the large Orange button labeled "Transmit my returns now".

After completing the File section and e-filing your tax return you will receive two emails from TurboTax. The first email when your tax return was transmitted and the second email when the tax return has either been accepted or rejected.
