Missed Notice 148A because of wrong/old email used to issue notice. What next?

RSKINDIA (Taxpayer) (32 Points)

05 April 2022  

Hello,
I was issued a notice u/s 148A on March 16 for the AY 2018-19. The email used to issue the notice was not mine, but of a consultant I hired to file ITR way back in 2015. From 2016 onwards I have filed my own ITR using my own email, which is reflected in the submitted ITR and is the same email registered on income tax portal. I have no idea why the notice was issued to an irrelevant email address. There was no physical notice issued.

Anyway, since the email used to issue the notice for AY 2018-19 was not mine, I did not receive email notification and the 7-day window for responding to the notice was closed on March 25. I found out about the notice yesterday after randomly logging into my account on portal and browsing casually. How do I deal with this now?
