Deductions & credits

I also have done back door Roth in 2020 for both the 2019 and 2020 tax years in January of  2020. 

 

I use the desktop version of TurboTax.  The step that was indicated did not work.  I did not have the opportunity to "choose to not deduct IRA contributions".  Would you help me with the steps for the desktop version. 

Thank you, Jim
