You should receive a Form 1099-R
showing the total amount of any distribution
from your IRA before income tax
or other deductions were withheld. This
amount should be shown in box 1 of
Form 1099-R. Unless otherwise noted in
the line 4a and 4b instructions, an IRA
includes a traditional IRA, Roth IRA,
simplified employee pension (SEP)
IRA, and a savings incentive match plan
for employees (SIMPLE) IRA. Except
as provided next, leave line 4a blank and
enter the total distribution (from Form
1099-R, box 1) on line 4b.
