I need to draw $20,000.00 from an anunity IRA and I want to know how much tax will be taken out of it?

You can have any amount that you want to be withheld for tax.

The actual tax on a Traditional IRA distribution  is determined when you file your tax return and depends on your marginal tax rate.   If you are in the 22% tax bracket, for example, then you probably should have 20% withheld.  If under age 59 1/2 and there will be an additional 10% penalty, then probably 30% withholding.

Actually, the amount withheld for federal taxes on a regular distribution from a traditional IRA  must either be 0%, 10%, or more than 10%.  10% is the default if you do not specify otherwise.
