Valid point...OP if you are over 55 there may be an exception to the penalty and if you are over 59 1/2 there is no penalty at all. You would just pay regular tax on the 20k.
OP should also be aware that some plans offer penalty free hardship distributions for people of any age. OP should discuss this option with the plan administrator to see if she may qualify.
You may qualify to take a penalty-free withdrawal if you meet one of the following exceptions:
•You become totally disabled.
•You are in debt for medical expenses that exceed 7.5% of your adjusted gross income.
•You are required by court order to give the money to your divorced spouse, a child, or a dependent.
•You are separated from service (through permanent layoff, termination, quitting or taking early retirement) in the year you turn 55, or later.
•You are separated from service and you have set up a payment schedule to withdraw money in substantially equal amounts over the course of your life expectancy. (Once you begin taking this kind of distribution you are required to continue for five years or until you reach age 59½, whichever is longer.)
