After you file

You can initiate the link from either app, though most people do it while choosing how to receive their refund.

Within TurboTax (During Filing)

1. This is the most common way to link them, especially if you want the Refund Advance or 5 Days Early refund features.
2. Reach the Refund section of your tax return (usually near the end).
3. Select Deposit to a Credit Karma Money™ account as your refund method.
4. TurboTax will prompt you to sign in to your Credit Karma account.
5. Follow the on-screen prompts to authorize the data sharing between the two accounts.

Within the Credit Karma App

If you haven't started your taxes yet, you can link them to import data.

1. Open the Credit Karma app.
2. Tap the "Tax" or "Money" tab in the bottom navigation bar.
3. Select "File with TurboTax" or "Get Started."
4. You will be asked to log in with your Intuit/TurboTax credentials. Once logged in, the accounts will be linked for the season.

Via "Switch Products" or "Tax Tools"

If you are already in TurboTax and want to link them before the "Refund" stage:

1. Go to Tax Tools > Tools on the left menu.
2. Look for a prompt or "offer" related to Credit Karma Money or Refund Advance.
3. Clicking these will usually trigger the account linking process.
