Federal tax amount is HUGE difference from last year and don't know why

My wife and I file jointly. We moved from CO to FL in December 2020, so we live in FL all of 2021. We both still worked for companies in CO. I know that all affects state taxes, but what I'm not understanding is why we go a decent return last year, but this year we are paying a few hundred. The number for AGI, Taxible Income, Total Tax, Total payments, and effective tax are are almost identical. We are baffled.

Start by checking your data entry carefully, especially commas and decimal points (which can look similar on a computer screen).  Were you assessed any tax penalties?

We've triple checked the numbers and even redid the whole thing from scratch several times, always with the same outcome. There were no notifications of any tax penalties from TurboTax and I'm not aware of any.
