After you file

Uh-oh...please clarify exactly what product you have been using.

 

Did you buy desktop software from Costco but used Online TurboTax by mistake or under the mistaken notion that they were interchangeable?   Did you not install and use the software you purchased? 

 

If you used Online TurboTax (web version) instead, the Online version has no connection with the desktop software, so that's why it is charging you again.   And since you referred to a "39.99 for refund processing", that is an extra service fee if you choose to pay any TurboTax fees out of your Federal refund, such as fees for an Online return.

 

We can tell you what you will have to do, when you confirm exactly what you have done.
