The responses to my questions on this amendment issue have been very helpful! I am almost wrapped up with this and ready to file my IL 1040X, but not sure how to show "proof that the IRS has accepted the Fed 1040X" Turbo Tax indicated in an email that "Your amended federal tax return was accepted by the IRS". The IRS site for "Status of My Amendment" shows "received" but indicates it could take 16 weeks to receive final approval. So what can I send to IL along with my Fed 1040X to show "acceptance"?
