There's nothing this board can do to help.
If you are locked out of your account (so you can't get a copy of this year's or last year's tax return), then you can try and verify your identity by answering questions based on your credit report files. If that doesn't work, you need to call customer support on Monday. The easier it would be for you to get into your account after forgetting your password, the easier it would be for someone else to get into your account by claiming to be you and forgetting your password.
Here is how to contact support on Monday. https://ttlc.intuit.com/replies/3300041
