If the return included the estimated payment, and showed that you more or less broken even, then you did owe the extra money, as it was counted with your other payments and credited to your account.
If the return did not include the estimated payment, then the IRS should show a large balance on your account. Sometimes they will automatically refund it, or they may apply it to next year. Check your tax return to see if the estimated payment was included. You can also check your IRS account balance here.
