Need information regarding tax on fixed deposit?

I have some 12lakhs. i wanted to invest it on a property next year. I am planning to deposit this amount in bank for 1 year.
I wanted to know about the tax deductions?
if i fill the TDS form will i be exempted from tax?
Which is a better way to invest i.e, investing the full amount in a single deposit or splitting the amount and depositing in different banks?
Please suggest some other investment plans where i can invest this amount other than FD for 1 year.
