NY State Witholding

I retired in 2018 and (other than ivestment income) I have income from a NY State Pension (which is exempt from NY State Tax) and Social Security. I owe a penalty on my 2019 taxes for underpayment of NY State tax. I don't believe I have any way to put in for NY State Witholding, correct?

I realize I could make estimated payments but I'm sure I'll forget.

Thanks.
