Partial Roth conversion with non-deductible contributions

I made a partial conversion from a Traditional IRA which included non-deductible contributions to a Roth IRA during 2020.  When TurboTax asks for my 2020 year-end balance in my traditional IRAs, do I include the amount that I converted to the Roth or just the remaining balance on 12/31?  Also, if I made a 2020 contribution to the Traditional IRA in January 2021, should I include that amount in the 2020 year-end balance?  Thank you
