Hello, can anyone going to university of hull september 2022 who has paid tuition deposit of 2k kindly give me a few info?

I am filling the form A, flywire gave a remittance/Reference number that needs to be included in the transfer. I can't seem to find any where on the form A to include this reference number. It starts with UHS.... if you have successfully finished this stage kindly let me know how you did your. Thanks.
