I just found this post about the exact same issue I'm having. Been a Turbo Tax Deluxe user for many years, using the CD version. Each year I E-file Federal, NJ and NY at the same time. Never had an issue until I tried to transmit my 2023 return yesterday. Interesting that the other person experiencing this problem posted just two days ago with the same issue resulting. That person's return, like mine, included a NY State return. I've cleaned out the cache and history in all my browsers and tried to transmit at least five times. When I hit the "Transmit Return" button, I get an error message from Intuit that says "Duplicate Filing found in same transmission. Please contact customer support. Tax Year 2023 transmissions are not available. Turbo Tax is not ready to process Tax Year 2023 for this return." Then I go to the "Check E-File Status" section of the Turbo Tax program and it tells me I have not yet E-Filed any of my returns (Federal, NJ, NY). I believe the problem lies with the NY State Division of Taxation server at this point. Rather than to try and E-File my Federal return separately first, then each state individually, I'll wait at least another few days to see if NY has corrected the problem and try transmitting all three of my returns at the same time again. Meantime, can the folks at Intuit/Turbo Tax check with the NY State Division of Taxation to see what they can find out regarding problems with accepting E-filed Turbo Tax 2023 returns on their end and post a response here to let us know if they confirmed that there's a problem on their end?
