I entered the 1099-R information. I called the financial to verify their federal identification number. I also asked for verification on the two codes P and J. They were hesitant to guarantee that those would be the codes but said they will probably be the codes.
As expected, my tax refund remains the same. I also notice that form 5329 is generated too. As you said, since the forms are not final yet, both 1040 and 5329 are shown as errors for that reason.
