How do I enter a backdoor Roth IRA conversion?

I have been using TurboTax for several years and I always have problems entering my backdoor Roth IRA conversion on the TurboTax online. My wife and I both put in $7,000 non-deductible after tax dollars into a IRA in 2021 and then immediately converted it to a Roth IRA. When I follow the two step process I must be missing something this year as it doesn't change my taxes and when I preview my 1040 (using Tax Tools then Tools) my Form 1040, Line 4a  is blank instead of showing the correct $14,000.
