Income tax refund

while checking income tax refund status for f.y.2016-17 its showing ITR processed.

Date of order 29/10/2018

DAte of Email-30/10/2018

but while checking the status on NSDL its showing A.O. has not sent your refund for processing.

how do i get to know if there is notice u/s 143?
