To enter the First Time Homebuyer's Credit:

1. Click on "Federal Taxes"
2. Go to "Deductions & Credits" 
3. Scroll down to "Your Home" click "show More" to the right
4. Click on "Start" next to "Homebuyer Credit Repayment"

When I click more on the deduction>My Home, I am only seeing 2008 first time home buyers credit and D.C Home buyers credit. Where do I find the standard federal first time home buyers credit

There isn't one for federal.  Unless you are thinking of the exemption to the 10% Early Withdrawal Penalty for taking a IRA Distribution to buy it.  Some states may have a credit.
