I found out how to fix the TurboTax default. Since the original request was rejected, it could not be processed. But TT assumes that it was. So if you go in and change the amount owed and paid back to what they should be then you can refile the extension request. I did that and it was then accepted. I had to change my AGI because the value TT used was wrong. I believe this will generate one request for payment.
