For Traditional IRA we used $10 K for First Time Homeowners (deducted $1,500 in taxes). We also withdrew IRA Roth Contributions. How do I document this?

You will enter each 1099R in TurboTax as separate transactions as they are.

I assume these are both early withdrawals (prior to age 59 1/2).  The distribution will all  be taxed on the traditional IRA, while $10,000 may be excluded from the 10% penalty.

You will credit for the $1,500 which should be on Box 4 of that 1099R.

On the Roth: 

 If the withdrawal is made before age 59 and 1/2 and is only up to the amount that has been contributed to the Roth IRA then no income tax is charged.

To enter each of these in TurboTax.
