IT Notice 142 and 148

SumitA (NA) (21 Points)

27 November 2019  

Hello all looking for some help with IT notice. 

Received section 142(1) and 148 in 2019 for assessment year 2011-2012.  Requesting verification of financial transaction and other information.
My question is if these notices are valid and can AO issue such notices after 7 years?
 

Thank you in advance.
