Wrong Last Name On Birth Certificate

Question:
So here is the thing about my last name. At the time of my birth, my mom put the wrong man (father) on my birth certificate and so my legal name is [name removed]. I didn't meet my dad until I was almost 2 years old. I don't understand my moms decision to put that man on my birth certificate when she didn't even take a paternity to prove he was for sure my father. (Note I've never met the man who is on my birth certificate.) But that's beside the point. The point is my mother never legally changed my name once she found my dad and took a paternity test to prove it. (She was the only one who had the power to change it, hence my actual father was not on my birth certificate so he had no power to. I haven't gotten around to changing it because it is more a financial hassle. But to make a long story short I've always gone by the last name [name removed] (my actual biological last name. Hence it is confusing because of my moms mistake). But my legal name is [name removed]. So my question is in my numerology profile would I just avoid the last name [name removed] since it was a clear mistake and it is not my identity? Everyone knows me by my last name [name removed], and it is embarrassing every time I have to explain why I have two last names. So would I include just [name removed]?
