To ensure you do the Roth IRA backdoor conversion and the contribution doesn't get marked as taxable income, I had to follow the instructions from this link:
"2. Inside TurboTax, search for ira contributions and select the Jump to link in the search results"
Only once I had followed the rest of the instructions and selected Yes, make part of my IRA contribution nondeductible and THEN returned to the 1099R upload section was I able to ensure that the Backdoor Roth IRA conversion was not counting as taxable income.
To confirm you've done everything correctly:
1) left hand side, go to tax tools -> tools
2) click view tax summary
3) left hand side -> preview my 1040
4) Section: "Form 1040 or Form 1040-SR, Lines 1 - 7" - line 4b should show you a taxable amount of 0.
I'm honestly amazed and how unintuitive TurboTax is. Hopefully this saves another person the 3 hours of wasted time that I lost.
