In a panic I decided to file for an extension but pay an estimated amount so that I didn't get hit with late fees. Turns out I had everything so I just went ahead and filed today. I'm worried that since I entered in my estimated payment info (with bank account) for my extension, AND did the same today when I actually filed, that I'll get charged twice. Is there a way to cancel my extension application to make sure I don't get charged twice?
