What is the $20 additional charge for listed under "Maximum Refund Guarantee"? I already have one free federal e-file and a $20 state filing fee.

As @TiffanyL mentioned. In the desktop software, there is a $19.99 fee to e-file a state return. The other fee is not for "Maximum Guarantee".  It's a service fee for the optional method of payment you chose. If you pay the $19.99 (plus possible sales tax) upfront with credit/debit card or a prepaid debit card you can buy in a store, there is no additional fee.

However, if you choose the option to pay the $19.99 fee out of your Federal refund, there is an additional $40 service fee. You can avoid that $40 or $45 fee by not selecting to pay your fees by that optional method and paying your 19.99 fee upfront directly by card. 

You can see what you are being charged for. Click on Tax Tools from the Menu on the left side in your return. Click Tools then My Fees.

@skidac5 If you are using the CD/download, there has been a fee to e-file the state return for years.   The software included the program to prepare the state return but there has been a fee to e-file the state.  The fee to e-file state is $20 and increases to $25 in March.   You can easily avoid the state e-file fee by printing and mailing the state.

@skidac5   Have you been using the Desktop program each year?  The free state has always been only to download 1 state PROGRAM, which can prepare unlimited state returns.   Then you have to buy any other different state programs at $40 like you did.

Then each state (including the first one) has always had a fee to efile.  It used to be 19.95 but went up to $20 a couple years ago.  Then the early fees expire on March 1 and go up to $25.   Or you can print and mail state for free.  If you don't remember paying for state efile you either mailed it or check your credit card records or you might have had it deducted from a federal refund (for which there is another EXTRA $39.95 Pay with Refund fee).

The $40 is a joke. You can save this Green Dot scam imo by filing the federal first. Then, wait 5 minutes and file your state separately. I still had to pay $20 for an Oregon state processing fee on my credit card but it was worth it for sure.

One disclaimer - if you file separately YOU HAVE to pay with a credit card. The option of having the $40 from your federal return goes away because you have already filed your federal. I wonder how much of a kickback TT is getting from GreenDot/Santa Barbara llc for this extra step. If you read the fine print for the $40 option, your money goes to GreenDot and then the $40 comes out and then the rest of your refund goes to your personal bank account. This is a Joke!!!
