Mine too was accepted by making the 1 penny change.
I had 5 total 1099R's, but only 2 had same payer and same amount (different payees). I changed 1 of them by a penny and the system took it.
The other 3 were all from the same payer to the same payee, so I originally thought that was the issue, but they had different amounts already.
More description of what is considered 'duplicate' would be really helpful, if anybody from TurboTax is reading these posts.
