I don't know which site you are sending the BTC to.
Whatever, you have given a BTC address & it must be unique; I mean no one else will have the same address for deposit. It's created for you only- that's how it works in other sites.
In that case, no matter how you send, your account will be deposited.
It would be better if you share a screenshot of the payment request so that someone can point out if there's any problem.
