Retirement tax questions

so based on my example numbers below from my original post

 

***********

 

I have made non deductible contributions to a Traditional IRA for years prior to 2019 (basis as of 12/31/2018 = $7200), and have never made deductible contributions to the Traditional IRA.

 

In 2019 I converted 7200 from the  Traditional IRA ( I only have 1 Traditional IRA) to my Roth IRA and also, for tax year 2019,  I am making a non deductible contribution of $6000  to the Traditional IRA in March of 2020.

After the 2019 $7200 withdrawal for the conversion and prior to the $6000 2019 (in 2020) contribution, the Fair Market Value as of   12/31/2019 was $5035 due to stock gains in  the account.

 

In filling the Taxable IRA Distribution worksheet line 4, should I enter:

a - $5035

or

b - $5035 + 6000 (2019 contribution in 2020) = $11035

 

*****

 

would the answer be a - $5035 or  b - $11035?
