Thanks for the quick response. Apparently the reason TurboTax wouldn't update the amount paid with the extension is that my original request for extension and payment were not through TurboTax. I discovered I could override the amount but there were all sorts of dire warnings that I really shouldn't do it.
I assumed IRS would eventually figure it out, but also assumed it would take a very long time for them to do so. I figured the best method to get the ball rolling would be through an amended return.
I guess we'll find out.
