How can I verify my TM30 submission and obtain the receipt if my landlord submits it online?

Tm30 confusion. I have a new passeport and immigration told me i have to do a new Tm30. I tell my landlord, she does it through the website [members only]/ However, she entered the wrong address... Immigration said this time it's ok, but she has to do it correctly for next time. My question is, how can i know that the Tm30 is correctly done and how can i have that piece of paper that you normally have in your passeport, if it's my landlord that does it online ? Thank you
