If you haven't filed then please follow these steps:
If you have already filed you can look at Schedule 1 line 19 IRA deduction if you have an entry here. Please see How do I get a copy of a return I filed this year in TurboTax Online?.
If you need to make changes to a filed return and your return has been already accepted by the IRS, you will have to file an amended return (1040X) to make changes. But you might want to wait until your refund or payment is processed. The IRS will only accept amended returns via mail.
The 1040X form for 2019 hasn't been approved yet by IRS. Please, keep checking the following information below on how to amend your return; it will be updated once the 2019 form is released. Currently, the form is scheduled to be released on 02/20/2020.

Thanks again!
