I owe $9***n in tax this year. Again because of a stock sale/capital gains event. That is clearly over the $1000 lower limit that is suggested to generate an "underpayment penalty" Since I did not know/foresee in 2019 that I would be selling stock and owing capital gains in 2020, Will I be charged an underpayment penalty?
Is there any way to avoid an underpayment penalty?
