Selling platforms....

Hi, this has probably been asked before but I cant find anything specific;

We're having a major clearcut out, my other half has finally convinced me its time.... anyway ive already sold over 40 items on vinted for approximately £100 on total. I claim new style/ contributon ESA and pip nothing means tested. I will have to submit an online form at the end of the year with my national insurance number as per the vinted guidelines. Will this have a negative effect on my circumstances? I terrified of getting in trouble or doing something im not supposed to.....

Thank you
