TDS credit is to be claimed in the year in which the income is offered to tax. So there is no need to revise the TDS return or the tax return for AY 2012-13. Also, in income tax return, there is option of claiming partial or full credit of TDS or to postpone to future years.
You will get the credit. Keep your Form 16A handy.

do you have the option? yes you have. You can revise the returns. But AO would ask for reason for reducing the income. Plus will your auditor give you revised audit report? Income is to be recognized on the basis of accounting policies of the entity. I would suggest that you maintain your claim and if the AO doesn't agree to it, then you go for revision. normally AO should n;t object as this is going to be revenue neutral adjustment.
