Probably the expenses you funded from the loan are at the least a mix pre-incorporation expenses, both operating and capital. These can be accounted for in the company even if they were prior to incorporation.

Those entries would result in a credit to your loan account and assuming all of the expenses qualify, just charge the same interest and the same terms as you are paying.

But you should get a qualified accountant to look at the actual nature of the stuff and see if and how it qualifies.
