Which amount to mention for Charity donation?

This is about the entry "Gift Aid payments made in the year to 5 April 2023" in the Self-assessment. Considering that our entry ticket to the museum was £27. When we opted for the GiftAid donation, the ticket price changed to £29.7. So is it £27 or £29.7 that we need to mention for the above entry in the self-assessment? The amount will be the same for the "Total of any 'one-off' payments from above" entry as well right?

Hi dijeah,
You should enter the price that you paid.
If this is not a regular amount you should enter it in the one-off payments box that you mentioned.
Thank you. 

Thanks
