Help needed for insta account

Hi folks, my instagram account has been deactivated for a while now but the thing is this morning I received multiple messages (two factor authentication code) on WhatsApp and email. I am unable to find who this person could be and how I can save my account because I have all of my memories there. This has also happened before and once my account was disabled by insta, probably due to mass reporting then I had to reclaim it and insta found no issues thereafter. I am kind of scared at the same time I want to find who this person could be. Is there any way I can find the location or the person who's trying to breach my account? Also, I already have two factor authentication on, is there anything else I should do to secure my account?
