Traditional IRA contribution to reduce adjusted gross income

I am doing my 2020 federal taxes.  Currently my AGI is $178,302.  I worked and contributed to a 401k retirement plan during the first 3 months of 2020.  I retired on 3/31/2020.  During those 3 months of employment I earned $38985.99 in wages and contributed $1850.50 to a designated Roth under a 401k plan.

 

I am interested in making traditional IRA contribution to reduce my AGI.  I am under the impression that I can make such a contribution of $0.00 up to $7,000.00 before April 15, 2021 and can apply that to the 2020 tax year.

 

If that is true, where do I specifically enter that contribution amount?  I am using Turbo Tax Deluxe.
