You potentially have two options. If you were eligible to make a Roth IRA contribution for 2019, you can ask the IRA custodian to recharacterize the contribution that was apparently actually made as a regular traditional IRA contribution to be a Roth IRA contribution instead. The custodian will move the gain or loss adjusted amount to the Roth IRA and your filed tax return will be in agreement with your contribution. Before requesting a recharacterization, make doubly sure that your modified AGI for the purpose is not so high relative to your filing status as to make you ineligible for any part of the resulting Roth IRA contribution.
Otherwise, you must amend your 2019 tax return to remove your entry of a Roth IRA contribution and enter it as a regular traditional IRA contribution instead. TurboTax will either include the contribution as deductible on Schedule 1, resulting in a refund of tax, or as a nondeductible contribution on Form 8606. (If the result is that the entire traditional IRA contribution is nondeductible, you can probably mail the Form 8606 stand-alone, without amending on Form 1040-X.)
