You were sent to the Credit Karma portal because, if approved, the refund advance is deposited in your Credit Karma checking account.

You can apply for a Refund Advance, with the loan amount based on the size of your federal refund. 

If approved, you will typically receive your Refund Advance into your Credit Karma MoneyTM checking account within 15 minutes of the IRS accepting your e-filed return.
