Your journal entries are correct.

The amount for adjusting entry is incorrect. You have only one note payable that is still outstanding. It is the 20 Aug transaction to Harris Motors. First you have to calculate the number of days from 20 Aug to 31 Dec, which is 133 days. Now take the principal amount of the note times the percentage rate of 12% times 133/360 days to get your interest expense and interest payable amount. The days after 31 Dec are not used in this calculation. When the note is paid you will have to calculate the amount of interest expense for the other 47 days, then add this amount to the interest payable to get the total amount of interest paid.

For your current liabilities section you are correct except that your Interest Payable amount is off. It will be the same amount that has been calculated above.
