Naturalisation Application -Lost Previous BRP

Hello everyone ,

I want to submit an online naturalisation application .I have a question to ask regarding evidence to be submitted with the application .
A little bit about myself :
I have been in the UK since 7 July 2006 with my famliy.I came here at the age of 15.I am now 30 years old .I am a diagnostic radiographer .I have had the following visas:
work permit dependant visa :2006-2010
Residence permit(via Flr o) :2011-2014
Residence permit (via FlR o) :2014-2018
Indefinite leave to remain :2018-now

I am applying for british citizenship via the 5 year residence .I lost the second BRP CARD (2014-2018).However , I have a stamp with BRP in my passport when i travelled in 2016.I have only travelled 5 days for the 15 years I have been in UK.I travelled to get a new passport .
I understand I have to submit evidence of residence five years from the day I submit the application .IF I HAVE LOST THE BRP CARD (2014-2018), WILL THIS NEGATIVELY IMPACT MY NATURALISATION APPLICATION?IS THE STAMP IN MY PASSPORT WITH THE BRP NUMBER SUFFICIENT,ALONG WITH A COVERING LETTER EXPLAINING ?I HAVE ALL MY VISAS BESIDES THE BRP FROM 2014-2018.
In case someone asks, i dont have a copy of this BRP.I have looked everywhere and I cant find it.
ALSO, CAN SOMEONE ALSO PLEASE SHED SOME LIGHT ON ALL THE DOCUMENTS I SHOULD SUBMIT FOR THE NATURALISATION APPLICATION>

Thank you in Advance,
Thandi
