1099-Q Distribution Code 1 is not an Option

I'm looking at a 1099-Q with a distribution code of 1.  Just 1. No words.

 

TurboTax wants me to choose between:

  • Distributions
  • Excess Contribution
  • Disability
  • Death
  • Prohibited Transaction

I may not be the brightest bulb in the bunch, but this has me stumped. Which TTax choice is the same as "1"?
