I was suggested to share my information with intuit to move faster with filing my taxes, by mistake clicked on 'No Thanks' and now I can't go back to start again.

Click the directions here to clear and start over. As long as you haven't submitted payment, deducted the TurboTax fee from your refund, or registered, you can erase your return and start from scratch in TurboTax Online.

I tried that and didn't work. I can't try anymore things. I ended up entering everything this time and I'm done with it.
