I bought my house in 2008. I took the $7,500 credit. I remembered that I have payed $500 each year in 1040.
Now I have to fill the tax form this year. How to fill the two textboxs.
From my friends at IRS.gov:
So, $7500 in first field, and you 'should' have paid $500 in 2010 and 2011, or $1000 total in second field.
