Is a distribution from my ROTH IRA counted as income?

Yes it is income reported on the 1040 form line 4a but probably not taxable income on line 4b.

In general, ROTH IRA distributions are not taxable.

However, there are exceptions:

If your Roth IRA is less than 5 years old, the earnings portion of the distribution is taxable, and if you are under 59 1/2, that earnings portion is also subject to the 10% early withdrawl penalty.
