I have paid a total of 100 dollars for my turbotax package and filed an extension. But i will not file my taxes with turbotax. Could I get a refund? will this affect ext?

You can request a refund by calling customer service at (800) 446-8848.

However, I don't know how successful you will be if you have merely changed your mind.

There is no charge for filing an extension, and your extension has already been processed, so your request will not impact this filing.
