Surprise Underpayment penalty

For my 2021 taxes, done with Turbo, I paid the full federal and state taxes that were due as computed at filing.

I paid the 4 computed Estimated taxes for Fed and State through 2022-23.

As I do my 2022 taxes, with Turbo, I got a note that I have to pay an underpayment (<$100) penalty for 2022!

I don't understand!!!
