After you file

Turbo Tax confirmed my amended Federal return was accepted on April 29. However, the IRS website indicates they are not processing a return and to contact my software provider. TurboTax indicates the IRS accepted my return. I created an account on the IRS website and it doesn't show anything pending either. If the IRS website showed I should wait that is fine but I fear they don't even have the amended return. What should I do? How can I confirm my 1040x form was submitted to the IRS?
