how did you get $81,500 contribution room? Did you get that amount from 2022 CRA re-assessment? When did you enter Canada?
You should withdraw all the excess amount immediately or risk a 1% penalty every month. You may have another interest penalty notice coming every month until you withdraw the money.
If 2022 CRA re-assessment made a mistake, call them up and see if they can remove the full or portion of the interest.

At any time in the year, if you contribute more than your available TFSA contribution room you will have to pay a tax equal to 1% of the highest excess TFSA amount in the month, for each month that the excess amount stays in your account. For more information, see Tax payable on excess TFSA amount.
