It - deductions under 80tta

Sir/Madam,

Under Deductions in IT returns ITR1, there's 80TTA Section for Interest from Bank Saving account or Post Office Saving scheme. What I wish to know is  Say if I am earning say Rs 6000 as interest from savings account, can this amount be included here under 80TTA? 6000 that I earned would already be included under total income from Interest/Other sources and then I claim deduction of Rs 6000 is this correct or this comes into effect only when your total interest from saving acct exceeds Rs 10000?

Thanks.
