It will probably be best to wait for correspondence from the IRS. If they process the first return, they'll notice you didn't include your previous tax estimates you paid, and will send you a "We corrected your return" letter with their adjustments. If you indicated a refund due you in your original filing, they will likely adjust that number up and tell you they will be sending you an increased refund amount. Compare their letter to your records to see if they did everything right. If that is the case, they may ignore your second filing. Sending the IRS a 3rd return, even if amended, may complicate things more than they already are.
