What do I enter in Box 2a for my IRA distribution?

For an IRA distribution, leave Box 2a empty if you don't know the taxable amount. Our software calculates taxable income by using the gross distribution you enter in Box 1 of the 1099-R screen and information you enter about your IRA account on the screens after the 1099-R screen.

Also make sure you check the IRA / SEP / SIMPLE box by Box 7 if it's checked on your Form 1099-R.
