Is it possible to get a income tax loan?

It might be possible somewhere, but not from TurboTax. TurboTax is not offering advance refund loans at this time. An advance might be offered when your tax return is complete and ready to file, including the information from your W-2 and all other tax forms. You don't actually get the advance until the IRS has accepted your tax return. The advance will be issued on a prepaid Visa card. See the FAQ at the following link for details.

About Refund Advance

REFUND ADVANCE

Last year for 2018 returns, certain qualified users were offered refund advance amounts on prepaid Visas at the time of e-filing, predicated on the amount of the refund and their returns being accepted by the IRS.  But it had to be offered--there was no way to opt in by request. If they offer a similar program for 2019 returns, do not expect to see it until January.  Since a return cannot be e-filed and accepted until the end of January, you could not receive a loan until early February at best.
