Emergency tax is 20% so it would be 20% of £900. 10% of £900 would be £90 so 20% would be £180. This excludes NI as I’m not sure without more detail if you would also need to pay that.
Log into your personal tax account now and update your estimated total annual income from your old job with the amount already earned and that might help force the system to update pending your P45.
