How returns are being processed in 2017: 

Now all details declared in your ITR w.r.t. Income (gross total income, taxable income, other income like interest income, etc.) / Deductions / TDS, are being matched with the details available in your Form 16 as well. If there is any variance in details given in ITR and Form 26AS / Form 16 / Form 16A, you would get an intimation u/s 143(1)(a) of the Income Tax Act.
