Retirement tax questions

First, thanks for replying.

I have a single member LLC (pass-through for tax purposes).  I set up a cash balance plan through the LLC and contributed money to it (let's say $100,000 for simplicity).  I have not been able to find a way to enter this in TurboTax.  The amount should end up on line 16 of Schedule 1 (as it is a "qualified plan").  I would appreciate guidance on how to enter it there.
