Is the amount in the 1099-R box 1 the same amount I would use to show how much of my roth ira distrubution I spent on one of the reasons listed?

Yes, If you did indeed use all of the funds for the same purpose it would be the amount in box 1.

I think you are referring to the questions:

• I moved the money to another retirement account
• I did something else with it

If you selected I moved the money to another retirement account there is an additional option to rollover only part of the money.

Maybe, but probably not.  The box 1 amount is the maximum for which you might claim an exception to the early-distribution penalty.  However, because you can take out your Roth IRA contributions (and Roth conversions that have met the 5-year holding period) without tax or penalty, it's likely that a substantial portion of this distribution is already free of tax and penalty and needs no penalty exception.
