Retirement tax questions

Hello! This is a follow up question. 


Apart from the four fields that you mentioned in your answer below, Turbotax is prompting me to provide "Payer's Federal Recipient's identification number" from the 1099-R as well. 
I won't receive a 1099-R until Jan 2019 so I don't have that information with me. I talked to Fidelity Retirement Services, they don't have this information either, they're saying they don't have any 1099-R generated yet, so they don't know that number yet. 

What should I do in this case?

Thanks!
