Since it's not a government-related pension, choose 'None of the above'. A later question may ask 'was this a 403b or other qualified plan', choose 'other qualified plan'. TurboTax may also ask about RMD. You can enter $0 or the total amount, even if RMD is not required for this type of distribution.
When entering the info from the 1099-R, in Box 7 enter 4 on the first line, and D on the second line.
Here's more info on 1099-R for Pensions, Annuities, Retirement.
