Select Edit for your New York return.
Continue until you reach Changes to Federal Income. On this screen, select Start next to Received retirement income.
On your Retirement Distributions Summary, select Edit next to the pension you’re reviewing.

I followed the exact steps you noted prior to posting question. It indicated no further info is needed. One source is pension of periodic payments that started in a prior year. Another source is RMD distribution. On the Changes to Income under Subtractions from Federal : Pension and Annuity Exclusion it does not show $20,000 as it has in previous years. I once again reviewed the Federal section for accuracy of information entered and all info matches the 1099-Rs.
