What is a periodic pension payment?

Periodic payments include substantially equal payments made at least once a year over the life of the employee and/or beneficiaries or for 10 years or more.

The program does ask if it was periodic payment or lump sum and what did you do with it. All of those questions are in the federal section. There is one question that is automatically checked none of the above and it would be easy to hit continue and go right past it.
