NJ State - Pension Income - Expected Return on contract

[Dom2]

My wife started receiving a small pension from GE as she worked there for a relatively short time.  Turbo tax is asking for the "Expected Return on Contract".  I have no idea what this is and/or how to calculate.  Please see the attached.  Any insight would be greatly appreciated.

Replying to my own question in case this helps someone else.   On the fed side I selected general rule which was forcing the state side to ask the question.  Once I removed the general rule selection the state side was fine, no longer asking me the question.
