Answer: The debit column of the trial balance was overstated.
Explanation: from the question, the asset purchased with a value of $18,950 was overstated in the asset asset account.
On the purchase of the asset, the asset account is to be debited and accounts payable account is to be credited and not debited. So the debit side of the trial balance was overstated by $18,950 * 2 = $37,900.
