Hello, wcswarriors.
Thank you for reaching out to the Community. Since these are lump sum payments you received from RaiseRight, you have to split the payments into different invoices so it will apply to the tuition income account.
For good practice, you can add or match your transactions to ensure they go to the right accounts. Once ready, you can now reconcile your account to make sure your books are accurate.
However, I suggest consulting an accountant. This is to ensure that your recordings are accurate and with no discrepancies in your book.
I'll be on the lookout for your reply and to further assisting you if you have other questions. Wishing you and your business continued success. Have a great day!
