Should we add money to our escrow?

So we’ve owned our house for one year now. About $230 goes to escrow every month. Earlier this year we received a check for an escrow overage of $883 earlier this year. Long story short, 2 months ago we received notice that we needed to pay our flood insurance policy and it turns out that someone at the bank dropped the ball and didn’t have our flood insurance policy included in the escrow. That’s all sorted out but now has left us with a negative balance of about -$550. Now this will get into the positive soon, but it makes me worried about having a shortage this year and our mortgage go up.
