Intiimation u/s 143 (1)

One of my client was having refund, I file his return but in Income Tax offline utility there was some problem , instead of deduction some expenses added in Profit automatically by that utility , till the time of submission there was showing refund, but after submission there was tax payable hence next day I revised the return, but that original return was e-verified and client received intimation u/s 143(1) showing demand. but that demand is incorrect, I file revised return please tell me what to do.
