RECFICATION UNDER SECTION 154 AND ITS REJECTION

I'm in the exact same situation for FY2017-18. Data in ITR and 26AS checks out, but getting rejections for revised returns and grievances.

Only place I suspect a mistake is the Schedule S for that year which looks weird and different from later years. In FY2017-18, they have asked for "Salary (Excluding all exempt/ non-exempt allowances, perquisites & profit in lieu of salary as they are shown separately below)" where I entered salary excluding perquisites minus allowance exempt u/s 10. Nowhere in the ITR utility have they calculated gross salary. But in the next year, they had added a non-modifiable column for  "Gross salary"

If OP was able to resolve the problem, can you please post the steps you took? 

Dear Madam, since we are into service industry (tour and travel industry) and do not have our own products, the earning is our turnover actually, but tds is deducted by customer on invoice value in case of tour/package invoices as per income tax law.

As the case is of technical glitches on portal, it is required to be check first before replying. Either to consult with some nearby CA or you can DM me.
