After you file

Hi Xmas, 

 

I really appreciate the quick response, unfortunately yes I've already filed my taxes. That's why I was trying to submit the amended form, but I wasn't seeing that option and it really threw me for a loop. This is the first time I've filed for an extension which I'm now regretting doing.  So, now I'm trying to see if I can make that change so I can make that payment so I don't get dinged and have to pay interest and or penalties. Also, I saw that one of the links you provided was for IRS payment plans, are you able to do a payment plan even when you've filed for an extension? Again I really appreciate your prompt response!
