Look back at the original listing does the item location have a UK address? Then, don't be fobbed off that it goes back to China, it goes back to the UK location.
You say ' doesn't fit'. Was it misdescribed, that is, they sent the wrong size item? Then, open a case for item not as described ... Does Not match Description or Photos, and seller here pays for the return postage.
If it simply does not fit but accurately described, if the seller has a returns accepted policy, you have to pay for that return postage, but again to the UK not China, if the location is described as above.
