@macuser_22 I think I've see you explain this better than I can.
@ansettax You are in a complex situation that is not to your benefit, and you really should have had financial advice before you tried to do a backdoor Roth in your situation. I have no idea if you can extricate yourself before the October 15 filing deadline, and it may be too late in any case.
When making a "back door" Roth conversion, you have to account for all your existing IRA balances. If you don't convert all your IRA balances to a Roth, then the backdoor gets very complicated. I can't explain it, but I found this article.

Workplace plans are not IRAs. Even though they have many similar rules, they are controlled by different sections of the tax law and some of the rules are very different. In your case, once you roll over your former 401(k) into an IRA, then it is an IRA, and the balance of this IRA will affect your ability to do a backdoor Roth. In Turbotax, you need to include all your IRA accounts, no matter how they were funded (but don't include qualified workplace accounts).
