Consequences of accidentally holding onto two Indian passports simultaneously?

Before marking this as a duplicate, please note:- I have already seen Two passport of the same person in India and the discussion there does not answer my query. That question is about a error in the passport department side and hence easily corrected by them, but in my case it is my/my family's mistake and I would like to know the consequences of that. Please read below.

When I went to the PSK Chennai for renewal of my passport (P1) which was about to expire in less than a year from now, I was shocked to learn that I have another passport (P2) issued under my name in RPO Lucknow almost 18 years ago (ie. during my college time). As I do not have any recollection of the exact events (probably due to my Vitamin D/calcium deficiency ?!) and since my father has unfortunately expired 9 years ago, I dont have the exact account of the events that has led to this situation. But I can try to explain to the best of my knowledge why I am in this situation based on the events from my memory. As I was only 18/19 years old at the time these events happened, I was simply signing where my father asked me to sign without understanding much about what was happening. So, in the write up below I am going to be implying that my beloved father did most of the things !

First, my Father (and I) had applied for Passport P1 for me in RPO Chennai (my place of residence). But we did not know about the status of our application for more than 6 months. Assuming that the application had got rejected, and anxious that I need a passport to pursue my higher studies, my father who has not had any formal school education of any sort, must have been instructed by some travel agent to apply for a passport (P2) near my place of study. At the end, Both passports P1 and P2 got delivered. My Father must have been aware that one should not USE two passports and hence with this good intention he must not have informed me about the existence of P2 and put P2 away somewhere safe. He must not have been aware that not only should one not USE two passports, one should NOT even POSSESS two passports.

Though I was aware that it is not correct for a citizen of India to hold two passports, I was NOT aware of the existence of two passports under my name. Only last week, while applying for renewal of passport I learned that there is P2 issued to my name in RPO Lucknow. Guided by the Assistant Passport Officer and the Granting Officer in PSK to sincerely search for P2 at home and surrender it, I did an extensive search of my father's belongings and found it (!!!) along with my father's spiritual books (which had been untouched since the expiry of my father).

• Will this affect the renewal of my primary passport P1, AFTER I surrender P2?
• Will there be any mention of this in my passport P1 (ie a black mark) potentially affecting my future travels ?
