I am a International Student, came to canada in Sept 2023, while creating CRA account it is asking to enter the amount in 15000 line.

If you have not previously filed a Canadian tax return, you will not have that information and will not be able to create a MyAccount till after you have filed a return. Your first return will need to be sent in by post so that the Canada Revenue Agency (CRA) will now be able to enter your information and create a file for you. Once you have a file with the CRA you will be able to create a MyAccount and you will also have the information requested on your filed return or Notice of Assessment which the CRA will send you after the assessment of your return.

Thank you for choosing TurboTax.
