@Federica34 from Airbnb help centre it says "If you need to make a claim on your security deposit, you can do so in the Resolution Center within 48 hours of your guest’s checkout date." I take it that Tuesday midnight onwards + 48 hours, that's when the deadline is at the latest. The earliest would be your checkout timing + 48 hours but I am not sure. Either ways, ask for an urgent quote and let them know your situation, or perhaps open up the issue without asking for a finalised claim like paying partially now and refunding the excess amount later/pay more again later.
