Retirement tax questions

Thanks macuser_22. Unfortunately, I followed your instructions exactly and it's still showing my nonworking spouse's contribution ($6,000) as taxable in the 1040 form.

Here's what I'm doing:

1. Start on "Traditional IRA and Roth IRA" screen
2. Check "Traditional IRA" for both me and my spouse. Leave Roth IRA unchecked.
3. Is This a Repayment of a Retirement Distribution? No
4. Tell Us How Much You Contributed: $6000
5. Tell Us How Much You Transferred: $0
6. Any Excess IRA Contributions Before 2019? No
   
7. Any Nondeductible Contributions to NAME's IRA? Yes
8. Let's Find Your IRA Basis. Total Basis As of December 18, 2018: $5500
   
   1. Explanation: I contributed $5500 on Dec 30 2018 and $6000 on Jan 2, 2019, then converted both to Roth.
9. Tell Us the Value of All Your Traditional IRA Accounts: $0
   
10. Is This a Repayment of a Retirement Distribution? No
    
11. [Spouse] Tell Us How Much You Contributed: $6000
    
12. [Spouse] Did You Change Your Mind? No
    
13. [Spouse] Any Excess IRA Contributions Before 2019? No
    
14. [Spouse] Any Nondeductible Contributions to NAME's IRA? Yes
    
15. [Spouse] Let's Find Your IRA Basis: $5500 (same as my own)
    
16. Income Too High To Deduct an IRA Contribution. Continue
    
17. [Spouse] Choose Not to Deduct IRA Contributions: Yes, $6000
    
    1. Note: changing this figure makes no difference. No matter what I put, my taxes don't change.
18. Your IRA Deduction Summary: $0
    1. If I put $0 in #17, this figure is $6000. But my 1040 still shows $6000 as taxable no matter what. The only way to get rid of the $6000 taxable is to delete my spouse's 1099-R entirely.

Any ideas? Thanks again.
