You should have reported the nondeductible traditional IRA contribution for 2021 on the 2021 tax return. TurboTax should have created the 2021 Form 8606 with the basis on line 14 to enter into the 2022 tax return. 

You will enter your nondeductible traditional IRA contribution for 2022 on your 2022 tax return (and can enter your basis from 2021 in step 7 and 8 if not automatically carried over):

1. Click on "Search" on the top right and type “IRA contributions” 
2. Click on “Jump to IRA contributions"
3. Select “traditional IRA”
4. Answer “No” to “Is This a Repayment of a Retirement Distribution?”
5. Enter the amount you contributed
6. Answer “No” to the recharacterized question on the “Did You Change Your Mind?” screen
7. Answer the next questions until you get to “Any Nondeductible Contributions to Your IRA?” and select “Yes” if you had a nondeductible contribution before this tax year.
8. Enter your basis in the Traditional IRA from your 2021 Form 8606 line 14 (if you had a basis in the prior year)
9. On the “Choose Not to Deduct IRA

To enter your conversion made in 2022:

1. Click on "Search" on the top right and type “1099-R”  
2. Click on “Jump to 1099-R”
3. Click "Continue" and enter the information from your 1099-R
4. Answer questions until you get to “Tell us if you moved the money through a rollover or conversion” and choose “I converted some or all of it to a Roth IRA”
5. On the "Review your 1099-R info" screen click "Continue"
6. Answer "yes" to "Any nondeductible Contributions to your IRA?" if you had any nondeductible contributions in prior years.
7. Answer the questions about the basis from line 14 of your 2021 Form 8606 and the value of all traditional, SEP, and SIMPLE IRAs
