How to Refile Taxes After a Mistake in Declaring Expenses?

Hi everyone,

I used TurboTax Online (Quebec) to file my taxes last year as a self-employed artist. This was my third time using TurboTax, and in the past, the results always matched what I expected when I filed with the government. However, this year, the result was very different, and the refund and payment amounts were off.

When I was filling out my taxes, the app showed that declaring all my expenses would result in a smaller refund, so I left some expenses out because it seemed better not to include them. Unfortunately, I later realized this wasn’t accurate, and now I need to refile my taxes to adjust this and include all my expenses.

Can anyone guide me on how to refile my taxes in TurboTax? Is there a specific process to follow?

Thanks in advance for your help!
