I just realised I have made a really stupid mistake on my returns for 2017, 2018 and 2019 and I need to know how to correct it. I am self-employed and instead of writing my name and address for my business (which I now realise is what I was supposed to do), I wrote the name and address of the business that pays me (I am a sub-contractor for them, I do not own that business). It does not change any of the amounts that I have entered, it's just that the name and address of the business are inaccurate. How can I correct this mistake? Thank you
