You can go to IRS but you will need to establish an account. If your problem is the same as mine you will find that your AGI is correct on the IRS site but still keeps rejecting. I attempted to talk to a person but could not get beyond the computer based assistant. The correct AGI was transferred from last years file but my return keeps rejecting which tells me it is probably a software problem. Did TurboTax use the 1040SR for you also?
