Hi Tina,
You can add donations to your donation form manually by using our Manual Donations add-on https://givewp.com/addons/manual-donations/
This will let you add the donation to any donation form from the admin dashboard and will let you choose the payment method, donor, date etc. This donation will also add up to the donation goal ( if you have enabled any ).
You can read the complete “how to” doc here: https://givewp.com/documentation/add-ons/manual-donations/
Let me know if you have any further questions.
Thank You 🙂
