If you mean you filed your tax return and forgot to include the New York retirement income on your return, you will have to file an amended return to correct that. You should wait until your return is processed and you receive your refund if applicable before you do that. You will see an option for that when you log into your TurboTax account.
You enter the Form 1099-R that your pension is reported on in the Wages and Income section of TurboTax, then Retirement Plans and Social Security, then IRA, (401)-K, Pension plan Withdrawals, Form (1099-R).
