Did your original filed return show a big tax due? Don't amend for the estimates. The IRS should eventually match them up to your tax return and send you a refund. Do you have proof you paid them like bank statements? I would wait on the IRS to adjust it. Or you can call them at 1-800-829-1040 but it's hard to get though.
VolvoGirl I think you are right. I should have left it alone and not try to amend and let the IRS correct it automatically. I did pay a lot early on. But the 2nd payment of seven thousand came out of the blue. It took me weeks before I discovered a big hole in my bank account. Right now I need to know what happened with the second amendment (a correction of a correction). and why I can't get a printout of it. There is a tax file that may be it but PDF won't open it.
