I have a similar problem. Turbo tax instructions say to complete the 1310 and then mail it in after efile. When it did the final review after I had paid all of the fees it wouldn’t let me efile and now it won’t let me complete the return. I spent several hours on the phone with 2 different tax experts with no resolve other than offering me a refund.Ask that they escalate this to a program person but haven’t received any response. The IRS publication is confusing but I interpret ot as saying that you CAN efile in this situation.
