Hello Eg White,
You will need to manually work out how much VAT you are due to claim back on these expenses manually, and then split the transaction between VAT & No VAT so that only the amount you are due to reclaim posts to your return.
This is the only way we can think to suggest, however we would advise to speak to an accountant to check if there's any further way they are aware of.
Thanks,
Talia
