If you owe an amount to repay an RSP withdrawal made for a Home downpayment or Life long learning, you will either have to make an RRSP contribution for 2018, or have the annual repayment treated as a permanent RSP withdrawal. At the moment, it seems you have opted for the second route.
You still have until Mar 01 2019 to make at least a 2018 contribution equal to your annual RRSP repayment amount.
